Stewart – Calculus 8e ET Chapter 5 Form A
14. You are given function f defined on an interval [a, b], the number n of subintervals of equal length
, and the evaluation points ck in .
(a) Sketch the graph of f and the rectangles associated with the Riemann sum for f on
[a, b], and
(b) find the Riemann sum.
, ck is the right endpoint
15. Evaluate .
16. Let .
a. Use Part 1 of the Fundamental Theorem of Calculus to find .
b. Use Part 2 of the Fundamental Theorem of Calculus to integrate to obtain an
alternative expression for F(x).
c. Differentiate the expression for F(x) found in part (b).
The Fundamental Theorem of Calculus, Part 1
If f is continuous on [a, b], then the function F defined by
is differentiable on (a, b), and
The Fundamental Theorem of Calculus, Part 2
If f is continuous on [a, b], then
where F is any antiderivative of f, that is, .
17. Evaluate the integral.
