Example Question #41 : Calculus Ii — Integrals

?

Possible Answers:

Correct answer:

Explanation:

Remember the fundamental theorem of calculus! If , then .

Since we're given , we need to find the indefinite integral of the equation to get .

To solve for the indefinite integral, we can use the reverse power rule. We raise the power of the exponents by one and divide by that new exponent. For this problem, that would look like:

Remember, when taking an integral, definite or indefinite, we always add , as there could be a constant involved.

Now we can plug that back in:

Notice that the 's cancel out.

Plug in our given numbers.

Example Question #43 : Calculus Ii — Integrals

Possible Answers:

Correct answer:

Explanation:

Use the Fundamental Theorem of Calculus: If , then .

Therefore, we need to find the indefinite integral of our equation first.

To do that, we can use the anti-power rule or reverse power rule. We raise the exponent on the variables by one and divide by the new exponent.

For this problem, we'll treat  as  since anything to the zero power is one.

Since the derivative of any constant is , when we take the indefinite integral, we add a  to compensate for any constant that might be there.

From here we can simplify.

That means that .

Notice that the 's cancel out.

From here, plug in our numbers.
