ahhh its pi/2?

Answer 6

It must be pi.

Answer 7

You are searching the angle whose secant is -1, or equilavently, whose 1/cos(x) is -1, or equivalently the angle where cos(x)=-1, that is pi.

Answer 8

Thanks for helping me with all of this, i really do appreciate it.

Answer 9

it is pi over 2, because you are looking for the arcsec, which is inverse secant.
