Math 106 Web Site Tips
Images
If you're familiar with HTML, you can include images using the usual
<img src=...> syntax, but it's preferred that you use the math ftp
site, so read on...
If you want to create a picture and include it in one of your postings, first
save it in GIF or JPEG format. You should then use an ftp program (such
as Fetch for the Mac, or WS_FTP for Windows) to send the file to
math.brown.edu, in the directory /pub/ma106. If you want you can create
a subdirectory for yourself, but if you don't know how, it's not
necessary.
Then, after the file is on the server, you can include the following code
in your posting:
<img src="ftp://math.brown.edu/pub/ma106/blah.gif">
Of course, replace "blah.gif" with your own filename. (It's best not to
put spaces in your filename.)
Applets
If you come up with something interesting in one of the applets in the
textbook, you can share it by clicking "Show Applet Tag" from the Window
menu of the Controls window, and cutting and pasting the text into your
posting.
Symbols
If you want to put a symbol like an integral sign into your posting, you can
type this:
which will appear like this in the discussion:
Here are some other symbols:
{ineq} | |
{gteq} | |
{lteq} | |
{sqrt} | |
{plusminus} | |
{dot} | |
{cross} | |
{partiald} | |
In addition, you can use the name of any Greek letter, as in
{alpha} for . (This feature is not yet 100%
supported under Unix, but it will be in a few days.)
Finally, to do a superscript or subscript, write {^2} for 2, or {_2} for 2 (where of course anything you want can go in place of the 2).
