Hi.
I am writing some vector formulas in LaTeX and cannot figure out how to get a line or a 'hat' (^) above a letter. I have asked a few, but they didn't know, so I hope one of you do, off the top of your heads.
I have not tried google, as I am not entirely sure what to search for, and no, I will not buy a fivehundred page LaTeX--book to figure out how to represent vectors
Sincerely,
-Kenneth Straarup.
