Hi

I am having a little bit of a mental lapse right now :cry: :zzz: :yuck: and I was wondering if someone could help me out.

I want to write the formula as

3(cos^2(x)sin^2(x)) to the identity sin2x = 2sinxcosx

Thanks ALOT!

Note that:
[tex]\cos^{2}x\sin^{2}x=(\cos{x}\sin{x})^{2}=(\frac{2\cos{x}\sin{x}}{2})^{2}[/tex]
