How to get started Writing on 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:MA375Spring2012Walther" 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.
  • Note: if you want to make a matrix, look at the source code for this page (click "edit") to see the syntax for the following matrix:

$ \left(\begin{array}{cccc}1&2&3&4\\5&6&7&8\end{array}\right) $
