//Advanced Modern Algebra//, revised, by Joseph Rotman, 2002.
!Course Content
Modern algebra may be considered the study of operations independent of the mathematical entities to which they are applied. This course will consider the symmetric and combinatoric structure that algebraic operations impose on the entities they act upon, and will focus in particular on groups, rings and fields. We shall encounter examples of these from the various number systems, polynomials, permutations, geometry, and linear algebra.
!Course Requirements
Attendance at each class meeting is necessary for success. You are encouraged to read the text diligently and peruse each section before it is discussed in class. Homework will be assigned and collected regularly. There will be a midterm and a comprehensive final exam. The midterm and final will each contribute 30% toward your course grade, and your combined homework grades will determine the remaining 40%.
!Plus/Minus Grading
A plus or minus may be used as a possible grade modifier, for final grades only, at the end of the semester. Factors that influence the assignment of a + or - (or neither) are: performance on the final exam, consistency of performance throughout the semester, proximity to a grade borderline, class participation and effort.
!Academic Expectations
In choosing UNCW, you have become part of our community of scholars. We recognize that the UNCW learning experience is challenging and requires hard work. It also requires a commitment to make time available to do that hard work. The university expects you to make academics your highest priority by dedicating your time and energy to training your mind and acquiring knowledge, and expects you to abide by the Academic Honor Code in the Student Handbook, Code of Student Life. Academic success in critical thinking and problem solving prepares you for the changes and challenges you will encounter in the future. Our faculty and academic support resources are readily available as partners in this effort, but the //primary responsibility for learning is yours//.
!Incompletes
A grade of I (incomplete) is given only if documented circumstances beyond the student's control (e.g., medical, legal) render the student unable to complete the course work, and only if there is a reasonable possibility of passing the course. The grade of I is not given for simply failing to meet the course requirements.
!Federal Americans with Disabilities Act
If you have a disability and need reasonable accommodation in order to participate fully in this course, you must be registered with the Office of Disability Services in Westside Hall (x3746). You need to provide your instructor a copy of your Accommodations Letter within the first week of class or as soon as possible. You should then meet with your instructor to make mutually agreeable arrangements based on the recommendations of the Accommodations Letter.

!Integration by Parts
*Recall that the product rule for differentiation states
<html>
<div class="math">
\frac{d}{dx} [ f(x)g(x) ] = f'(x)g(x) + f(x)g'(x).
</div>
</html>
*Integrating, we find that
<html>
<div class="math">
\int f(x)g'(x)dx = f(x)g(x) - \int g(x)f'(x)dx.
</div>
</html>
*Making the substitutions $u = f(x)$ and $v = g(x)$, we obtain
<html>
<div class="math">
\int u \ dv = uv - \int v \ du.
</div>
</html>
-s-
!Example
*Consider $\int x \ \sin x \ dx$.
*We must choose $u$ and $dv$ appropriately to apply the integration by parts formula.
*In this case, we may choose $u=x$ and $dv=\sin x dx$.
*Then we have
<html>
<div class="math">
\begin{eqnarray} u & = & x & \quad & dv & = & \sin x \ dx \\
du & = & dx & \quad & v & = & -\cos x \end{eqnarray}
</div>
</html>
*It follows that <html>
<div class="math">
\begin{eqnarray} \int x \sin x \ dx & = & x \cdot -\cos x - \int -\cos x \ dx \\
& = & -x \ \cos x + \int \cos x \ dx \\
& = & -x \ \cos x + \sin x + C \end{eqnarray}
</div>
</html>
-s-
!Example
*Consider $\int x^2 \cos x \ dx$.
*In this case, we may choose $u=x^2$ and $dv=\cos x \ dx$.
*We then have
<html>
<div class="math">
\begin{eqnarray} u & = & x^2 & \quad & dv & = & \cos x \ dx \\
du & = & 2x \ dx & \quad & v & = & \sin x \end{eqnarray}
</div>
</html>
*It follows that
<html>
<div class="math">
\begin{eqnarray} \int x^2 \cos x \ dx & = & x^2 \cdot \sin x - \int \sin x \cdot 2x \ dx \\
& = & x^2 \sin x - 2 \int x \sin x \ dx \\
& = & x^2 \sin x - 2 [ -x \ \cos x + \sin x ] + C \\
& = & x^2 \sin x + 2x \ \cos x - 2 \sin x + C \end{eqnarray}
</div>
</html>
-s-
!Choosing Parts
Two criteria to keep in mind as you apply integration by parts:
# $v$ should be easy to find from $dv$
# the integral $\int v \ du$ should be easier to evaluate than $\int u \ dv$.
In general, choosing $u$ according to the acronym LIATE will help to satisfy the second criterion.
-s-
!LIATE
LIATE is an acronym for
<<tiddler LIATE>>
Choose for $u$ the part of the integrand that appears first in LIATE and let $dv$ be whatever is left in the integrand.
Better to choose $u$ LIATE than never!
-s-
!Example
Consider $\int \cos^{-1} x \ dx$.
*Take $u=\cos^{-1} x$.
-s-
!Example
Consider $\int e^x \ \cos x \ dx$.
*Take $u=\cos x$.
-s-
!Example
Consider $\int x \ \ln x \ dx$.
*Take $u=\ln x$.
-s-
!Example
Consider $\displaystyle \int_{0}^{\pi/2} x \ \sin x \ dx$.

!Description<html><a name="Description"/></html>
With the {{{<part aPartName> ... </part>}}} feature you can structure your tiddler text into separate (named) parts.
Each part can be referenced as a "normal" tiddler, using the "//tiddlerName//''/''//partName//" syntax (e.g. "About/Features"). E.g. you may create links to the parts (e.g. {{{[[Quotes/BAX95]]}}} or {{{[[Hobbies|AboutMe/Hobbies]]}}}), use it in {{{<<tiddler...>>}}} or {{{<<tabs...>>}}} macros etc.
''Syntax:''
|>|''<part'' //partName// [''hidden''] ''>'' //any tiddler content// ''</part>''|
|//partName//|The name of the part. You may reference a part tiddler with the combined tiddler name "//nameOfContainerTidder//''/''//partName//. <<br>>If you use a partName containing spaces you need to quote it (e.g. {{{"Major Overview"}}} or {{{[[Shortcut List]]}}}).|
|''hidden''|When defined the content of the part is not displayed in the container tiddler. But when the part is explicitly referenced (e.g. in a {{{<<tiddler...>>}}} macro or in a link) the part's content is displayed.|
|<html><i>any tiddler content</i></html>|<html>The content of the part.<br>A part can have any content that a "normal" tiddler may have, e.g. you may use all the formattings and macros defined.</html>|
|>|~~Syntax formatting: Keywords in ''bold'', optional parts in [...]. 'or' means that exactly one of the two alternatives must exist.~~|
<html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>
!Applications<html><a name="Applications"/></html>
!!Refering to Paragraphs of a Longer Tiddler<html><a name="LongTiddler"/></html>
Assume you have written a long description in a tiddler and now you want to refer to the content of a certain paragraph in that tiddler (e.g. some definition.) Just wrap the text with a ''part'' block, give it a nice name, create a "pretty link" (like {{{[[Discussion Groups|Introduction/DiscussionGroups]]}}}) and you are done.
Notice this complements the approach to first writing a lot of small tiddlers and combine these tiddlers to one larger tiddler in a second step (e.g. using the {{{<<tiddler...>>}}} macro). Using the ''part'' feature you can first write a "classic" (longer) text that can be read "from top to bottom" and later "reuse" parts of this text for some more "non-linear" reading.
<html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>
!!Citation Index<html><a name="Citation"/></html>
Create a tiddler "Citations" that contains your "citations".
Wrap every citation with a part and a proper name.
''Example''
{{{
<part BAX98>Baxter, Ira D. et al: //Clone Detection Using Abstract Syntax Trees.//
in //Proc. ICSM//, 1998.</part>
<part BEL02>Bellon, Stefan: //Vergleich von Techniken zur Erkennung duplizierten Quellcodes.//
Thesis, Uni Stuttgart, 2002.</part>
<part DUC99>Ducasse, Stéfane et al: //A Language Independent Approach for Detecting Duplicated Code.//
in //Proc. ICSM//, 1999.</part>
}}}
You may now "cite" them just by using a pretty link like {{{[[Citations/BAX98]]}}} or even more pretty, like this {{{[[BAX98|Citations/BAX98]]}}}.
<html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>
!!Creating "multi-line" Table Cells<html><a name="TableCells"/></html>
You may have noticed that it is hard to create table cells with "multi-line" content. E.g. if you want to create a bullet list inside a table cell you cannot just write the bullet list
{{{
* Item 1
* Item 2
* Item 3
}}}
into a table cell (i.e. between the | ... | bars) because every bullet item must start in a new line but all cells of a table row must be in one line.
Using the ''part'' feature this problem can be solved. Just create a hidden part that contains the cells content and use a {{{<<tiddler >>}}} macro to include its content in the table's cell.
''Example''
{{{
|!Subject|!Items|
|subject1|<<tiddler ./Cell1>>|
|subject2|<<tiddler ./Cell2>>|
<part Cell1 hidden>
* Item 1
* Item 2
* Item 3
</part>
...
}}}
Notice that inside the {{{<<tiddler ...>>}}} macro you may refer to the "current tiddler" using the ".".
BTW: The same approach can be used to create bullet lists with items that contain more than one line.
<html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>
!!Creating Tabs<html><a name="Tabs"/></html>
The build-in {{{<<tabs ...>>}}} macro requires that you defined an additional tiddler for every tab it displays. When you want to have "nested" tabs you need to define a tiddler for the "main tab" and one for every tab it contains. I.e. the definition of a set of tabs that is visually displayed at one place is distributed across multiple tiddlers.
With the ''part'' feature you can put the complete definition in one tiddler, making it easier to keep an overview and maintain the tab sets.
''Example''
The standard tabs at the sidebar are defined by the following eight tiddlers:
* SideBarTabs
* TabAll
* TabMore
* TabMoreMissing
* TabMoreOrphans
* TabMoreShadowed
* TabTags
* TabTimeline
Instead of these eight tiddlers one could define the following SideBarTabs tiddler that uses the ''part'' feature:
{{{
<<tabs txtMainTab
Timeline Timeline SideBarTabs/Timeline
All 'All tiddlers' SideBarTabs/All
Tags 'All tags' SideBarTabs/Tags
More 'More lists' SideBarTabs/More>>
<part Timeline hidden><<timeline>></part>
<part All hidden><<list all>></part>
<part Tags hidden><<allTags>></part>
<part More hidden><<tabs txtMoreTab
Missing 'Missing tiddlers' SideBarTabs/Missing
Orphans 'Orphaned tiddlers' SideBarTabs/Orphans
Shadowed 'Shadowed tiddlers' SideBarTabs/Shadowed>></part>
<part Missing hidden><<list missing>></part>
<part Orphans hidden><<list orphans>></part>
<part Shadowed hidden><<list shadowed>></part>
}}}
Notice that you can easily "overwrite" individual parts in separate tiddlers that have the full name of the part.
E.g. if you don't like the classic timeline tab but only want to see the 100 most recent tiddlers you could create a tiddler "~SideBarTabs/Timeline" with the following content:
{{{
<<forEachTiddler
sortBy 'tiddler.modified' descending
write '(index < 100) ? "* [["+tiddler.title+"]]\n":""'>>
}}}
<html><sub><a href="javascript:;" onclick="window.scrollAnchorVisible('Top',null, event)">[Top]</sub></a></html>
!!Using Sliders<html><a name="Sliders"/></html>
Very similar to the build-in {{{<<tabs ...>>}}} macro (see above) the {{{<<slider ...>>}}} macro requires that you defined an additional tiddler that holds the content "to be slid". You can avoid creating this extra tiddler by using the ''part'' feature
''Example''
In a tiddler "About" we may use the slider to show some details that are documented in the tiddler's "Details" part.
{{{
...
<<slider chkAboutDetails About/Details details "Click here to see more details">>
<part Details hidden>
To give you a better overview ...
</part>
...
}}}
Notice that putting the content of the slider into the slider's tiddler also has an extra benefit: When you decide you need to edit the content of the slider you can just doubleclick the content, the tiddler opens for editing and you can directly start editing the content (in the part section). In the "old" approach you would doubleclick the tiddler, see that the slider is using tiddler X, have to look for the tiddler X and can finally open it for editing. So using the ''part'' approach results in a much short workflow.

|Name|Plugin: jsMath|
|Created by|BobMcElrath|
|Email|my first name at my last name dot org|
|Location|http://bob.mcelrath.org/tiddlyjsmath.html|
|Version|1.5.1|
|Requires|[[TiddlyWiki|http://www.tiddlywiki.com]] ≥ 2.0.3, [[jsMath|http://www.math.union.edu/~dpvc/jsMath/]] ≥ 3.0|
!Description
LaTeX is the world standard for specifying, typesetting, and communicating mathematics among scientists, engineers, and mathematicians. For more information about LaTeX itself, visit the [[LaTeX Project|http://www.latex-project.org/]]. This plugin typesets math using [[jsMath|http://www.math.union.edu/~dpvc/jsMath/]], which is an implementation of the TeX math rules and typesetting in javascript, for your browser. Notice the small button in the lower right corner which opens its control panel.
!Installation
In addition to this plugin, you must also [[install jsMath|http://www.math.union.edu/~dpvc/jsMath/download/jsMath.html]] on the same server as your TiddlyWiki html file. If you're using TiddlyWiki without a web server, then the jsMath directory must be placed in the same location as the TiddlyWiki html file.
I also recommend modifying your StyleSheet use serif fonts that are slightly larger than normal, so that the math matches surrounding text, and \\small fonts are not unreadable (as in exponents and subscripts).
{{{
.viewer {
line-height: 125%;
font-family: serif;
font-size: 12pt;
}
}}}
If you had used a previous version of [[Plugin: jsMath]], it is no longer necessary to edit the main tiddlywiki.html file to add the jsMath <script> tag. [[Plugin: jsMath]] now uses ajax to load jsMath.
!History
* 11-Nov-05, version 1.0, Initial release
* 22-Jan-06, version 1.1, updated for ~TW2.0, tested with jsMath 3.1, editing tiddlywiki.html by hand is no longer necessary.
* 24-Jan-06, version 1.2, fixes for Safari, Konqueror
* 27-Jan-06, version 1.3, improved error handling, detect if ajax was already defined (used by ZiddlyWiki)
* 12-Jul-06, version 1.4, fixed problem with not finding image fonts
* 26-Feb-07, version 1.5, fixed problem with Mozilla "unterminated character class".
* 27-Feb-07, version 1.5.1, Runs compatibly with TW 2.1.0+, by Bram Chen

MAT 542 Modern Algebra II
<<slideShow>> - A simple slide show that keeps the TW style
<<slideShow style:'MySSStyleSheet' clock:'+'>> - A themed slide show with a clock showing the presentation elapsed time
<<slideShow repeat clock:'-20'>> - A looping slide show with a 20 minutes countdown clock
<<slideShow slidePause:1000>> - A timed slideshow that runs once
<<slideShow slidePause:1000 repeat>> - A timed looping slideshow
-s-
!The [[SlideShowPlugin]]
Press F11 to go fullscreen and adjust the font sizes with Ctrl++ Ctrl+- (or Ctrl+mousewheel).
This plugin was developed by Paulo Soares and Clint Checketts.
{{Comment{This block is not shown in the slide show.
@@Don't show me!!!@@}}}
-s-
!How slides are separated
In a tiddler, you start each slide with the markup {{{-s-}}}
-s-
Slides don't have to have titles like this poor one but can have images.
[img[photos/lisboa-0.jpg]]
-s-
!A slide with subsections and a long title
Check to TOC below to see how this slide title is abbreviated.
!!Section 1
This is a section
!!!Subsection 1.1
This is a subsection
!!!Subsection 1.2
This is another subsection
!!!!Subsubsection 1.2.1
This is a subsubsection
-s-
!Using the keyboard
The following keys are defined:
*Left arrow - previous overlay
*Down arrow - previous slide
*Right arrow - next overlay
*Up arrow - next slide
*Home - first slide
*End - last slide
*Escape - exit slide show
*Spacebar - pause/resume slide show in auto advance mode
-s-
!Slide show parameters
*The slide show can be themed by providing a ~StyleSheet ({{{<<slideShow style:'MyStyleSheet'>>}}})
*By default, there is a clock at bottom of the browser window that displays the current time. This clock can also show the presentation elapsed time with {{{<<slideShow clock:'+'>>}}} or a countdown clock with {{{<<slideShow clock:'-20'>>}}} (for 20 minutes). In these two cases, if you click on the clock display it will be restarted
*The slide show can be set to loop ({{{<<slideShow repeat>>}}})
*You can set it so each slide changes after X milliseconds ({{{<<slideShow slidePause:X>>}}}) (auto advance mode)
*Use auto start mode to begin the slideshow the moment the tiddler is opened ({{{<<slideShow autostart>>>}}})
*You can disable overlays with {{{<<slideShow noOverlays>>}}}
*These parameters can be mixed and matched in any order: {{{<<slideShow slidePause:1000 repeat>>}}} is the same as {{{<<slideShow repeat slidePause:1000>>}}}
-s-
!Overlays
To see how incremental display works use the left and right mouse buttons.
{{Overlay1{You can}}} {{Overlay2{present things}}} {{Overlay1{in an arbitrary order!!!}}}
{{Overlay3{Its a bit harder with lists but it works:}}}
<html>
<ol>
<li class="Overlay4">First item</li>
<li class="Overlay5">Second item</li>
<li class="Overlay4">Last item</li>

!Description
This plugin turns a TiddlyWiki tiddler into a simple slide show type display. Most features that are usually found in presentation software are available. It should work in a way that does not interfere with TiddlyWiki. When you close the slide show you get back to your good old TW.
This plugin has been tested in Firefox and Internet Explorer. Let me know if something seems broken.
!Usage
To use this plugin you //must// be using TiddlyWiki 2.0. Some optional features (as the incremental display) require version 2.0.8 or higher. To install the plugin copy the tiddlers SlideShowPlugin, SlideShowPageTemplate and SlideShowViewTemplate to your TW, label the first one with the //systemConfig// tag, save the TW and refresh the browser.
To make a slide show simply drop {{{<<slideShow>>}}} at the beginning of a tiddler and use {{{--s--}}} to start each slide.
If you move your mouse over the bottom of the browser window you will see a few navigation buttons, a clock and a table of contents that shows up when you click the slide number.
Any block of text marked as {{{{{Comment{For my eyes only!}}}}}} will not be displayed in the slide show.
See these and other features in this [[SlideShowExample]].
!Incremental display
A succession of overlays (or layers) can be defined in each slide by marking blocks of text with {{{{{Overlay1{...some text...}}}}}}, {{{{{Overlay2{...some text...}}}}}}, {{{{{Overlay3{...some text...}}}}}}, ...
To costumize the way overlays are shown you can redefine the following CSS classes
*contentWrapper.slideShowMode .previousOverlay
*contentWrapper.slideShowMode .currentOverlay
*contentWrapper.slideShowMode .nextOverlay
in a ~StyleSheet. The default style simply hides the next overlays and shows the current and the previous ones as normal text.
!Slide show parameters
*The slide show can be themed by providing a ~StyleSheet ({{{<<slideShow style:'MyStyleSheet'>>}}})
*By default, there is a clock at bottom of the browser window that displays the current time. This clock can also show the presentation elapsed time with {{{<<slideShow clock:'+'>>}}} or a countdown clock with {{{<<slideShow clock:'-20'>>}}} (for 20 minutes). In these two cases, if you click on the clock display it will be restarted
*The slide show can be set to loop ({{{<<slideShow repeat>>}}})
*You can set it so each slide changes after X milliseconds ({{{<<slideShow slidePause:X>>}}}) (auto advance mode)
*Use auto start mode to begin the slideshow the moment the tiddler is opened ({{{<<slideShow autostart>>>}}})
*You can disable overlays with {{{<<slideShow noOverlays>>}}}
*These parameters can be mixed and matched in any order: {{{<<slideShow slidePause:1000 repeat>>}}} is the same as {{{<<slideShow repeat slidePause:1000>>}}}
!Slide show navigation
You can navigate through a slide show using the keyboard or the mouse. To quickly move to titled sections you can use the table of contents.
!!Mouse navigation
Left (right) clicking on a slide jumps to the next (previous) overlay. To move to the beginning of the next or previous slide you must use the navigation bar at the bottom of the browser's window. If there are no overlays defined both operations are equivalent.
!!Keyboard navigation
The following keys are defined:
*Left arrow - previous overlay
*Down arrow - previous slide
*Right arrow - next overlay
*Up arrow - next slide
*Home - first slide
*End - last slide
*Escape - exit slide show
*Spacebar - pause/resume slide show in auto advance mode
!Revision history
*1.5.1 10/11/2006
**added SlideShowPageTemplate and SlideShowViewTemplate. This way, the plugin no longer requires a standard TW layout. Thanks to Andrew Lister for the idea.
*1.5.0 18/09/2006
**fixed restoring stylesheet on exit
**changed (again!) the way how slides are separated (slide shows prepared for previous versions must be fixed)
*1.4.0 20/04/2006
**changed the way how slides are separated (slide shows prepared for previous versions must be fixed)
**now works with content included with the {{{<<tiddler>>}}} macro
**added incremental display (overlays)
**improved documentation
**assorted small fixes
*1.3.1 10/03/2006
**removed empty slide titles
**fixed wrong numberSlides when slides have div's
**fixed wrong time in Windows
*1.3.0 26/02/2006
**restore open tiddlers on exit
**fixed problem with markup in headers (should work with NestedSlidersPlugin)
**added slide comments (blocks of text in the tiddler that don't show up in the presentation)
*1.2.1 28/01/2006
**pause timed slideshow with spacebar
**added clock with 3 different modes
**fixed bugs with style and abbreviation options
**general cleanup
*1.2.0 07/01/2006
**added a resume feature
**added themes support
*1.1.5 14/12/2005
**added mouse support
**cleaned up navbar generation
*1.1.0 12/12/2005
**added support for IE
**added key listeners
*1.0.0 11/12/2005
**initial release
!Todo
*Time code is still very hackerish and unreliable.

|Name|ToggleSideBarMacro|
|Created by|SaqImtiaz|
|Location|http://tw.lewcid.org/#ToggleSideBarMacro|
|Version|1.0|
|Requires|~TW2.x|
!Description:
Provides a button for toggling visibility of the SideBar. You can choose whether the SideBar should initially be hidden or displayed.
!Demo
<<toggleSideBar "Toggle Sidebar">>
!Usage:
{{{<<toggleSideBar>>}}} <<toggleSideBar>>
additional options:
{{{<<toggleSideBar label tooltip show/hide>>}}} where:
label = custom label for the button,
tooltip = custom tooltip for the button,
show/hide = use one or the other, determines whether the sidebar is shown at first or not.
(default is to show the sidebar)
You can add it to your tiddler toolbar, your MainMenu, or where you like really.
If you are using a horizontal MainMenu and want the button to be right aligned, put the following in your StyleSheet:
{{{ .HideSideBarButton {float:right;} }}}
!History
