  1. 4-3 definite integrals Ms. Battaglia – ap calculus

  2. Definite integral • A definite integral is an integral • with upper and lower bounds. The number a is the lower limit of integration, and the number b is the upper limit of integration.

  3. Theorem 4.4 (Continuity implies Integrability) • If a function f is continuous on the closed interval [a,b], then f is integrable on [a,b].

  4. The first fundamental theorem of calculus • If f is continuous on the closed interval [a,b] and F is the indefinite integral of f on [a,b], then

  5. Evaluating a definite integral

  6. Areas of common Geometric Figures • Sketch the region corresponding to each definite integral. Then evaluate each integral using a geometric formula. • a. b. c.

  7. Definition of two Special integrals • If f is defined at x = a, then we define • If f is integrable on [a,b], then we define

  8. Evaluating definite integrals

  9. Additive Interval Property • If f is integrable on the three closed intervals determined by a, b, and c, then

  10. Using the Additive inverse property

  11. Properties of Definite Integrals • If f and g are integrable on [a,b] and k is a constant, then the function of kf and f + g are integrable on [a,b], and • 1. • 2.

  12. Evaluation of a definite integral • Evaluate using each of the following values.

  13. Preservation of Inequality • If f is integrable and nonnegative on the closed interval [a,b], then • If f and g are integrable on the closed interval [a,b] and f(x) < g(x) for every x in [a,b], then
