I'm just playing with Python 2.3, trying to get re-acquainted, and i've come across an extremely dumb problem, I don't know how to un-cosine (?) an angle on anything other than my calculator
I'm just writing something to solve some simple geometry (yeah, I'm pretty bored...), and when writing something to solve the formula:
cos (angle) = (a.b) / (|a|*|b|)
I can't get the angle because I don't know any function in any language equivalent to what cos^-1 would do on my calculator
Anybody know how to do it?
