**Find the integral...Please HELP!!!!**

## Homework Statement

Find the integral involving sin, cos, sec, and tan:

**A.**sin^3x * sqrt(cosx)dx

**B.**sec^3(2x) * tan(2x)dx

## Homework Equations

## The Attempt at a Solution

I will start with part A first...

**A.**sin^3x * sqrt(cosx) dx

sin^2*x * sqrt(cosx) * sinx dx

(1-cos^2*x) * sqrt(cosx) * sinx dx

sinx * sqrt(cosx) - sinx * cosx dx

but not I don't know what to do??
