Hmm, bit stuck on the Sine rule in C.

This is my statement to work out Sin A of the sine rule ;

Now I need to inverse sine that statement, but I can't work out how to do it.Code:SinA1 = ((Sina * sin(SinB * PI /180)) / Sinb) ;

I tried ;

But it miserably failed.Code:SinA1 = asin(((Sina * sin(SinB * PI /180)) / Sinb)) * PI / 180) ;

Any help?
