Determine whether each equation is true for all x for which both sides of the equation are defined. If it is true, support your conclusion with a sketch using the unit circle. If it is false, give a counterexample.

inverse sin(-x)=-inverse sin(x)

inverse cos(-x)=-inverse cos(x)

I think that the first one is true and the second one is false but I do not know what to put down as a sketch or counterexample. Any help is appreciated.
