Lesson #99
The Fundamental Theorem of Calculus and Properties
of the Definite Integral




Quote of the Day:

"It is clear that Economics, if it is to be a science at all, must be a mathematical science ... simply because it deals with quantities... As the complete theory of almost every other science involves the use of calculus, so we cannot have a true theory of Economics without its aid."
-- W. S. Jevons

2. The Fundamental Theorem of Calculus

Each branch of mathematics has a fundamental theorem associated with it.

The Fundamental Theorem of Arithmetic:
Any positive integer can be represented in exactly one way as a product of primes.

The Fundamental Theorem of Algebra:
Every polynomial of degree n has exactly n zeros.

The Fundamental Theorem of Geometry:
No theorem wears this title, but perhaps the Pythagorean Theorem deserves it.

The Fundamental Theorem of Calculus — there are actually two parts to this theorem:

The First Fundamental Theorem of Calculus:
The derivative of the integral of a function is equal to the function.

The Second Fundamental Theorem of Calculus:
The integral of the derivative of a function is is equal to the function evaluated at its endpoints.

The F.T.C. tells us that we can evaluate a definite integral by taking an indefinite integral and substituting in the endpoints and taking the difference:



Remember that you can't spell FUNDAMENTAL without FUN (and MENTAL, and DA). So, think of The Fundamental Theorem of Calculus as DA MENTAL FUN.
