: what have you tried already?
: I am not going to attempt an answer for this without more info on what you have attempted and why. This is too extensive a problem to explain without more info!
I'm stuck after getting this far:
Sin(x+y)Cos(y) >= Sin(x)
Sin(x)Cos(y)Cos(y) + Cos(x)Sin(y)Cos(y) - Sin(x) >= 0
Sin(x)(Cos(y)Cos(y) - 1) + Cos(x)Sin(y)Cos(y) >= 0
