Integration
Definite Integrals
Definite Integrals are calculating the area under a curve over a specific interval.
Notation: 
This also happens to be the fundamental theorem of calculus, given that f is continuous on (a, b) and F` = f
Note: There is no need for the +c because there would be a +c on F(b) and one on F(a) so they would cancel each other since F(a) is being subtracted fro F(b).
For example:
4.1 
4.2 
4.3 
4.4
