Integration with Chain Rule
Introduction
Integrating with the chain rule is the opposite of taking the derivative with the chain rule. For the derivative of the chain rule, 
.
So 
For example:
1.1 
=
1.2 
1.3 
1.4 
1.5 
The same holds true for trigonometric functions too.
For example:
2.1 
2.2 
2.3 
2.4 
2.5 
2.6 
2.7 
2.8
