5.3 The Fundamental Theorem of Calculus

Fundamental Theorem of Calculus: Let \(f\) be a function that is continuous on a closed interval \([a,b]\).

5.4 Properties of the Definite Integral

Properties of definite integrals:

If two functions \(f\) and \(g\) are continuous on the closed interval \([a,b]\) and \(k\) is a constant, then

Definition: The average value of a function over an interval \([a,b] \) is \(\bar{y}=\dfrac{1}{b-a}\int_{a}^{b}f(x)\,dx\)  (p. 374)
