Definite Integrals
What is the difference between a definite integral and an indefinite integral?
A definite integral is an integral calculated between two limits(values). So an definite integral returns an value as the answer whereas an indefinite integral returns an function as the answer.
The process of solving an definite integral can broken down into three steps:
Note: When you sub in the result of the integration, there is no need to include the +c inside the square brackets.
Example 1:
