B). The Fundamental Theorem DEFN: THE DEFINITE INTEGRAL If f is defined on the closed interval [a,b] and exists, then

B). The Fundamental Theorem The Definition of the Definite Integral shows the set-up. Your work must include a Riemann’s sum! (for a representative rectangle)

The Fundamental Theorem of Calculus (Part A) If or F is an antiderivative of f, then

REM: The Definite Integral is a NUMBER -- the Net Accumulation of Area or Distance -- It may be positive, negative, or zero. The Fundamental Theorem of Calculus shows how to solve the problem! Your work must include an anti-derivative!

Practice: Evaluate each Definite Integral using the FTC. 1) 2). 3). The FTC give the METHOD TO SOLVE Definite Integrals.

Example: SET UP Find the NET Accumulation represented by the region between the graph and the x - axis on the interval [-2,3]. REQUIRED: Your work must include a Riemann’s sum! (for a representative rectangle)
