so is that a yes?

integral sign sin^5(2x)cos(2x)dx
its multiple choice
OpenStudy (anonymous):
u-substitution
OpenStudy (anonymous):
u= Sin(2x)
du= 2Cos(2x)
\[1/2\int u^5 du\]

Use the washer method to find the volume of the solid generated by revolving the region bounded by the parabola y=x^4 and the line y=8x about the y-axis.

Whenever you have an integral of the form \[\huge \int \sin^m(x) \cos^n(x) dx\] and either \(m=1\) or \(n=1\), the technique is ALWAYS \(u\)-substitution.

bobchen - were you able to set up the integral for that second problem you wrote?
