Basic pointers

In order to do any editing, you must be logged in.

If you look under MediaWiki FAQ, you get lots of instructions on how to work with Rhea. Some important things are under item 4 in that manual.

If you want to do things like $\sum_{i=1}^\infty 1/i^2 = \frac{\pi^2}{6}$ in Rhea then you should look a) at the "edit" button on this page and b) get acquainted with Latex [1], a text-formatting program designed to write math stuff.

Here is some more math, to show you mathsymbol commands:

$\forall x\in{\mathbb R}, x^2\ge 0.\qquad \exists n\in{\mathbb N}, n^2\le 0$ where ${\mathbb N}=0,1,2,\ldots$

If you want to make a new page, all you need to do is to invent one. For example, let's say I want to make a page for further instructions on how to deal with Rhea. I just type "double-left-square-bracket page with more instructions double-right-square-bracket", where of course I use the actual brackets. The effect is: I get a link (initially red_MA375Fall2008walther) to a page that is the empty set. Once I click it, the link page with more instructions_MA375Fall2008walther turns blue and I am transferred to a newborn page of name as indicated.

Note: it may take a few minutes for the new page to start existing. If you click the red link and nothing happens, wait a bit and try again.

All your contributions are recorded by Rhea. To see all your contributions, look in the upper right to a link that says "My contributions" and click on it. You can also see another user's contributions.

To edit your User page, click on the link in the upper right which says your user name. For example, User:Walther

To message someone on the site, post to their talk page. For example, User_talk:Walther_MA375Fall2008walther (Keep in mind this is only viewed by logging on to kiwi)

Ideas for posting_MA375Fall2008walther

Week 1

For this week, click this link here and on that new page create a page as outlined above. Then move to that page and state your favorite theorem. Why is it your favorite theorem? Have other people the same favorite theorem? Crosslink! Use the math-environment if appropriate.

Week 3

For week 3: post and discuss the notion/theorem that you have found hardest to understand so far. Alternatively, find somebody else's post and reply to it by explaining how you understand things.

Further idea: discuss how quotations/citations/references should be handled on a Rhea.

Week 5

Post your solution to exercise 54 of section 5.5 on Rhea here, keeping your solution apart from everybody else's. Also, make sure you post an email address (this will be come relevant for next week's Rhea activity). Please make this your own solution only, don't look at other people's. There will not be credit on that question. This is an exercise in growing up.

Week 6

Find another student in class, and in pairs grade each other's Rhea post from week 5. Post your grading comments into the posted solution of that student, using signatures.

Final Exam

The final exam is Wednesday, December 17th from 10:20am to 12:20pm. The exam location is University 303.

Would anyone be interested in a study session or two before the final exam?
- Wednesday night of Dead week
I think the night before the exam would be a good idea as well
