I know that COSX is antisymetric about x=pi/2 but there is tan^-1 there, what about it ?
(sorry for beeing annoying)
Hello Phoebe,
I've attached a diagram of your function. You'll notice that it is antisymmetric as CaptainBlack stated.
In the drawing the value of the integral is called a.

cos(x) is anti-symmetric about pi/2, and tan^-1 is antisymnetric about 0,
which is what we need to conclude that the composite function is anti-
symmetrix about pi/2, since cos(x) maps pi/2 to 0.
