Integration with Chain Rule
U Substitution
An alternative way of finding more complex chain rule integrals is by using u substitution. In this instance we substitute terms of u in for a terms of x. Then we substitute in du for dx. Where du = u` and dx = x`. The next step is integrating the new equation. Lastly you substitute back in terms of x for terms of u.
For Example:
3.1 
3.2 
3.3 
3.4
