SOLUTION: Basically this is Trigonometric Identities. The question is: Simplify the expression sin^3(x)+cos((pi/2)-x)cos^2(x) I haven't gotten very far. So far I have: sin^3(x)+si

Question 307228: Basically this is Trigonometric Identities.
The question is: Simplify the expression sin^3(x)+cos((pi/2)-x)cos^2(x)
I haven't gotten very far. So far I have:
sin^3(x)+sin(x)*cos^2(x). I am so lost afterwards. Please help me.
Thanks!

good so far ___ just one more step

factoring out sin(x) ___ sin(x) [sin^2(x) + cos^2(x)]

anything look familiar?...
