The Fundamental Theorem of Calculus Inverse Operations
Fundamental Theorem of Calculus • Discovered independently by Gottfried Liebnitz and Isaac Newton • Informally states that differentiation and definite integration are inverse operations.
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
Guidelines for Using the Fundamental Theorem of Calculus • Provided you can find an antiderivative of f, you now have a way to evaluate a definite integral without having to use the limit of a sum. • When applying the Fundamental Theorem of Calculus, the following notation is used
Guidelines It is not necessary to include a constant of integration C in the antiderivative because they cancel out when you subtract.
Definite Integral Involving Absolute Value • Evaluate
Using the Fundamental Theorem to Find Area • Find the area of the region bounded by the graph of y = 2x3 – 3x + 2, the x-axis, and the vertical lines x = 0 and • x = 2
The Mean Value Theorem for Integrals • If f is continuous on the closed interval [a, b], then there exists a number c in the closed interval [a, b] such that
Average Value of a Function • This is just another way to write the Mean Value Theorem (mean = average in mathematics) • If f is integrable on the closed interval • [a,b], then the average value of f on the interval is
Finding the Average Value of a Function • Find the average value of • f(x) = sin x on the interval [0, p]
Force • The force F (in newtons) of a hydraulic cylinder in a press is proportional to the square of sec x, where x is the distance (in meters) that the cylinder is extended in its cycle. The domain of F is • [0, p/3] and F(0) = 500.
Force • (a) Find F as a function of x. F(x) = 500 sec2 x (b) Find the average force exerted by the press over the interval [0, p/3]
Second Fundamental Theorem of Calculus • If f is continuous on an open interval I containing a, then, for every x in the interval,
Second Fundamental Theorem of Calculus • Find F’(x) of
