## anonymous 3 years ago Evaluate the following integral:

1. anonymous

$\int\limits_{}^{}\sin^24xcos^24xdx$ (If possible, say which identities/formulas you are using)

2. calculusfunctions

Are those exponents 3 or 2? It's hard to tell with the equation editor?

3. anonymous

they are 2's

4. calculusfunctions

The power of sine looks like a 2 but the power of cosine looks like a 3.

I'd use the formula that says that 2sin(x)cos(x)=sin(2x) Then the integrand gets sin^2(8x)/4 and now that is easy to calculate by parts
