There is a simple way: Draw the graphs for the arcsin(x) & arccos(x), The x-coordinate of the point of intersection is the solution.

How do we go about that? it's just a matter of being familiar with both functions. has range has range the ranges intersect in quad I ... the angle in quad I that has the same sine and cosine value is if you insist on doing it algebraically ... ... the negative solution is invalid since and
