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!
