MA 265: "Linear Algebra", Professor Walther, Fall 2012

If you create a page that belong to this course, please write

[[Category:MA265Fall2012Walther]] 

at the bottom of the page.

OTHERWISE NO CREDIT ! (If you use the "Create a child page" button, this should happen automatically...)


Newsflash

  • Want to promote yourself to potential employers? Join Rhea's e-portfolio team! Purdue Freshmen-graduate students welcome. Contact rheateam@gmail for more info.
  • See under [[1]] for a symposium on the writer Jorge Luis Borges (1899-1986) whose work is

connected to mathematics and physics. The event (October 3) will feature mathematicians, physicists and writers discussing Borges and his work.

  • See Media:JPURFlyer2012.pdf for a workshop on Oct 17, 2012 on writing successful proposals for an article in Purdue's Journal for Purdue Undergraduate Research




Software requirement

Firefox version 2 is not good enough to see several things on Rhea pages. Use version 3 or higher.

How to get started with Rhea

  • Getting started
    • To start, click the "Help" button above and read what's there.
    • To edit pages, first log in (with your purdue account to create pages. Then click "edit" (under "Page" above) and remember to click "Save Page" after you are done editting.).
    • To get a quick idea what works how, click "edit" on this page to see how to do the things visible on this page.
    • Note that the "edit" mode has a spell-checking feature: look for red-underlined stuff.
  • Creating pages
    • To create a new page named "B" from a page A, go to edit page A and insert the text [[B]]. (Note that "B" is like a web address for a webpage. Each page also has a name, but you can call the link anything (like fancy_title) by typing [[B|fancy_title]] rather than just B. After saving, find the new red link on page A that appeared. When you click it, you'll note you are now on page B (which of course is empty at this point).
    • NOTE: if the "new" link comes out blue, instead of red, you chose a title of an existing page and did not create a new one. The blue link gets you simply to the already existing one. Use distinctive names for your new creations!
    • If you place "Category:MA265Fall2012Walther" enclosed by square brackets on top of a new page it will be parsed by the system as belonging to this course. It can then be searched (for) in a meaningful way.
  • Advanced Rhea techniques
    • You can look at other Rhea pages by clicking "main page" and then "course pages". Especially the ECE pages will get you an idea where one can take Rhea...

WebAssign

  • Q: How does one pay the access fee if one does not have the code straight from the textbook?
    • A: Contact webassign via phone!

Your turn! A bonus point opportunity

Students in MA265 Fall 2011 (Walther) have the opportunity to earn bonus points by contributing a Rhea page on a subject related to linear algebra. To pick a subject, simply write your name next to it. Please no more than one student per subject. Your page will be graded based on content as well as interactions with other people (page views, comments/questions on the page, etc.). The number of links to other courses and subjects will also be taken into account: the more the merrier! Please do not simply copy the lecture notes and do not plagiarize. Read Rhea's copyright policy before proceeding.

For some lovely contributions, see the "honors project" at the end of the page.
