I have to prove a trig identity with Maple for class. It's rather simple, but I can't figure out how to get the right-hand side into the form I want. What I have is:

 

tan(x)^2*sin(x)^2 = sin(x)^4/cos(x)^2

 

I simply want to convert sin(x)^4/cos(x)^2 into tan(x)^2*sin(x)^2.

The conversion is apparent to anyone looking at it but I simply cannot figure out how to put it in the right form, and I can't change the left-hand side due to the nature of proving a trigonometric identity.
