### Example Question #1 : Interpretations And Properties Of Definite Integrals

If , then which of the following is equal to ?

**Possible Answers:**

**Correct answer:**

According to the Fundamental Theorem of Calculus, if we take the derivative of the integral of a function, the result is the original function. This is because differentiation and integration are inverse operations.

For example, if , where is a constant, then .

We will apply the same principle to this problem. Because the integral is evaluated from 0 to , we must apply the chain rule.

The answer is .
