To evaluate the integral, we use the fact that the antiderivative of is (because ), and the antiderivative of is (because ). Using this information, we determine that the integral is

### Example Question #32 : Antiderivatives Following Directly From Derivatives Of Basic Functions

Calculate the following integral.

**Possible Answers:**

**Correct answer:**

Calculate the following integral.

To do this problem, we need to recall that integrals are also called antiderivatives. This means that we can calculate integrals by reversing our integration rules.

Thus, we can have the following rules.

Using these rules, we can find our answer:

Will become:

And so our answer is:
