The Fundamental Theorem of Calculus, Part 2
If f is continuous over the interval [a, b] and F (x) is any antiderivative of f (x), then
| f (æ) dæ = F (b) – F (a).
5.17
We often see the notation F (x)I to denote the expression F (b) – F (a). We use this vertical bar and associated limits a and b
to indicate that we should evaluate the function F (x) at the upper limit (in this case, b), and subtract the value of the function
F (x) evaluated at the lower limit (in this case, a).
The Fundamental Theorem of Calculus, Part 2 (also known as the evaluation theorem) states that if we can find an antiderivative
for the integrand, then we can evaluate the definite integral by evaluating the antiderivative at the endpoints of the interval and
subtracting.
Proof
Let P = {x;},i = 0, 1,..., n be a regular partition of [a, b] . Then, we can write
F (b) – F (a) = F (x„) – F (xo)
= [F (x„) – F (x„-1)] + [F (x,-1) – F (x„ 2)] + ...+ [F (x1) – F (xo)]

[F (x;) – F (x;-1)] .
Now, we know F is an antiderivative of f over [a, b] , so by the Mean Value Theorem (see The Mean Value Theorem) for
i = 0,1,..., n we can find c; in [x;_1, x;] such that
F (x;) – F (x;-1) = F'(c;) (x; – ¤;-1) = f (c;) Aæ.
Then, substituting into the previous equation, we have
F (b) – F (a) =
Taking the limit of both sides as n → 00, we obtain
F (b) – F (a)
