To type the letter 'å' in normal text more in LaTeX, one can write:
Code:
\r{a}
(if you enble the correct package, you can type a normal å as well)

But how do i use the character 'å' in math mode? The rules are different for characters in mathmode, for example here's how to type 'ä':
Code:
$ \ddot{a} $
What is the command for a ring?

Most of you americans here probably haven't encountered this problem.
