Consider the integral

This is an indefinite integral, so we need to find the most general antiderivative of the integrand f(x).

To find an antiderivative of f(x), we go through our list of integration methods:

1. Recognize elementary antiderivatives
   
2. Rewrite the integrand to make it easier
   
3. Use substitution to reverse the chain rule or simplify the integrand
   
4. Use integration by parts
   
5. Use inspection to see the value of a definite integral
   

to find one that works for this integrand. In this case, only one method is appropriate. We use basic antidifferentiation to determine the antiderivative. This is shown below.

Basic antidifferentiation:
In this case, by using rules for basic antiderivatives we can just write down the antiderivative of the integrand:
