e.g. I want to find y when x is at pi/2 for the graph y=cos pi x. Why does pi/2 have to be expressed as a 'normal' (for want of better word) number (3.14/2) and not as 90 degrees (180/2) like you would for a graph without a pi in it
e.g. cos x
For cos x, if x is at pi/2, then I just put in pi/2 in degrees
I get the feeling that the explanation is super obvious but I just don't see it yet
