I'm stuck -- all I can get is sin4x

or sin2x(1 - cos2x)

... but that's it ...

BJ.....I'm not sure what is wanted here.....notice that

sin^2x sin^2x   =

sin^4x

Or....this could equal

(1-cos^2x)(1-cos^2x)  =

1 - 2cos^2x + cos^4x

Other forms are possible......but the first answer of sin^4x   seems the most simple......(???)

Hey guys! Thank for your help!

Your suggestions and answers were not what the teacher was looking for, even though I got the exact same thing. However, I did end up getting the correct answer!

Thanks!
