Anyone remember their Trig and DiffEqs better than I do? Wanna help me with a problem? I have the following two equations:

A = asin(cos(X)*cos(Y))
B = atan(cos(X)*sin(Y)/(-sin(X)))

I know the values of A and B. I need to calculate values for X and Y. I tried some substitutions to simplify, but I just ended up with something uglier that I have no clue how to solve once I isolate a variable:

tan(B) = sin(A) * tan(Y) / (-sin(acos(sin(A)/cos(Y))))

Any suggestions?
