Fundamental Theorem of Calculus Sec. 5.4 (with a little from 5.3)
might well be your choice. Here is my favorite calculus textbook quote of all time, from CALCULUS by Ross L. Finney and George B. Thomas, Jr., ©1990. If you were being sent to a desert island and could take only one equation with you, might well be your choice.
The Fundamental Theorem of Calculus, Part 1 If f is continuous on , then the function has a derivative at every point in , and
First Fundamental Theorem: 1. Derivative of an integral.
First Fundamental Theorem: 1. Derivative of an integral. 2. Derivative matches upper limit of integration.
First Fundamental Theorem: 1. Derivative of an integral. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant.
First Fundamental Theorem: New variable. 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: 1. Derivative of an integral. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant.
1. Derivative of an integral. 2. Derivative matches upper limit of integration. 3. Lower limit of integration is a constant.
The upper limit of integration does not match the derivative, but we could use the chain rule.
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.
Neither limit of integration is a constant. We split the integral into two parts. It does not matter what constant we use! (Limits are reversed.) (Chain rule is used.)
