cos^2 x = 1 - sin^2 x
so
sin^2 x [ 1 - sin^2 x ] + sin^4 x
I think you can see what happens now :)
Hi. Can someone help me with this?
Simplify:
(sin^2x)(cos^2x)+(sin^4x)
The answer is sin^2x, but I have no idea how to get there!
Thanks!

Or....
take out a common factor
sin^2 x(cos^2 x + sin^2 x)
= (sin^2 x)(1) and there it is.
