why is it that arcsin(-y) = -arcsin(y) and that arccos(-y) = π (pi) - arccos(y)? also, what does the above 2 equations have anything to do with even and odd functions? i have no idea what is even and odd functions by the way.. thank you!!

An even function is a function such that . For example, a parabola is an even function since: An odd function is on in which Since the sine funciton is odd, the arcsine function is also odd. Therefore,
and what about for arccos?
