1. 4.4 The Fundamental Theorem of Calculus
Evaluate a definite integral using the Fundamental theorem of Calculus.
Understand and us the Mean Value Theorem for Integrals.
Find the average value of a function over a closed interval.
Understand and use the Second Fundamental Theorem of Calculus.

2. The Fundamental Theorem of Calculus relates differentiation and integration. Informally, the theorem states that differentiation and integration are inverse operations. Differentiation: Slope of tangent line = Δy/Δx Definite integration: Area under curve = ΔyΔx

3. ∫ f(x)dx = F(b) – F(a) Fundamental Theorem of Calculus
If a function f is continuous on the closed interval [a,b] and F is an antiderivative of f on the interval [a,b], then
∫ f(x)dx = F(b) – F(a)
Proof

4. Guidelines for using Fundamental Thm. Of Calculus
If you can find an antiderivative of f, you can now evaluate a definite integral without the limit process!!!
Use the following notation
It is not necessary to include a constant of integration C in the antiderivative because
