Question

How would I solve this problem? Find sin^-1(sin((7pi)/4))

I know that sin(sin^-1(x)) = x but can you do the reverse? Just need a little help on the steps of this problem

Answer 1

sin^-1 has a limited domian/range

Answer 2

sin(x) is a ratio between 1 and -1

sin^(-1) is an angle between -pi/2 and pi/2
