1. Evaluate We need to find a function, , such that
We know that
So we need to find a constant, , such that
Solving for , we get
So
Check your answer by taking the derivative of the function you've found and checking that it matches the integrand:
2. Find the general antiderivative of the function . We know that
We need to find a constant, , such that
Solving for , we get
So the general antiderivative will be
Check your answer by taking the derivative of the antiderivative you've found and checking that you get back the function you started with:
