How to inverse Sinus?

I need to calculate the inverse sinus of an equation.
Sinus is simple, but there don't seem to be any inverse funktion of sinus (or tan and cos for that matter).
How do I do that?

The functions for arcsine, arccosine, and
arctangent are ASIN, ACOS, and ATAN. (They are
also known as inverse sine, cosine, and targent.)

Good luck!
