You mean to use the inverse tangent function, but ask yourself, what is ?

oh i see now! tan goes to infinity at pi/2 and negative infinity at -pi/2 so the inverse tan of infinity is therefore pi/2

and the inverse tan of negative infinity would be -pi/2

is that right? - October 22nd 2012, 07:52 PMMarkFLRe: why is arcsin of t = to pi/2?
Yes, that is spot on! :)
