Determine if the statement is true or false if it is false provide a counter example.
arcos (cosx)= x for all values of x
I am not sure what exactly I am supposed to for example if I chose o the arc cos would be pi/2 and if I chose arc cos zero the angle would be pi/2. So would that mean this statement is true or is it false?

=\cos(x))

So would that mean this statement is true or is it false?![\displaystyle \arccos\left[\cos\left(\frac{3\pi}{2}\right)\right] \ne \frac{3\pi}{2}](http://latex.codecogs.com/png.latex?\displaystyle \arccos\left[\cos\left(\frac{3\pi}{2}\right)\right] \ne \frac{3\pi}{2})
