8-8.
Remember that the integral 'undoes' the derivative.But notice that you are integrating as a final step: don't forget +C.
Recall that e4x + 2 = e2e4x and e2 is a constant.
Before integrating, rewrite the integrand so it is not a fraction.
Use u-substitution.
u = sin²x
Before integrating, expand the integrand.
