1. 5.4 Second Fundamental Theorem of Calculus

2. If you were being sent to a desert island and could take only one equation with you, might well be your choice. Here is my favorite calculus textbook quote of all time.

3. The Fundamental Theorem of Calculus, Part 1 If f is continuous on, then the function has a derivative at every point in, and

4. Second Fundamental Theorem of Calculus: 1. Derivative of an integral.

5. 2. Derivative matches upper limit of integration. Second Fundamental Theorem of Calculus: 1. Derivative of an integral.

6. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant. Second Fundamental Theorem of Calculus:

7. 1. Derivative of an integral. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant. New variable. Second Fundamental Theorem of Calculus:

8. 1. Derivative of an integral. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant. The long way: First Fundamental Theorem:

9. 1. Derivative of an integral. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant.

10. The upper limit of integration does not match the derivative, but we could use the chain rule.

11. The lower limit of integration is not a constant, but the upper limit is. We can change the sign of the integral and reverse the limits.

12. Neither limit of integration is a constant. It does not matter what constant we use! (Limits are reversed.) (Chain rule is used.) We split the integral into two parts.
