For example, integrate sin(4x) dx. I find the derivative of the inner function which is 4 and I even it out by multiplying the whole package by 1/4. The integral of sin is -cos so it's -1/4cos4x.

This is a very simple example and I'm looking for websites that show much harder examples that use this technique. The problem is that most calculus tutorial sites seem to use u-subs or integration by parts to show how to do the more complicated examples.
