Essential Stuff Essential Question
What are definite integrals and how do you evaluate them? Essential Vocabulary Riemann Sum Definite Integrals Antiderivative
3
Riemann Sums Used to find area under a curve…
Divide interval in equal subintervals Draw rectangles with endpoints on curve (either left or right) or midpoints on curve Gives approximate area… more rectangles means better estimate. Calc in Motion Animation
4
The Definite Integral Riemann Sums The Definite Integral
5
The Definite Integral a and b are limits of integration
(a is lower limit and b is upper limit) f(x) is integrand
6
The Definite Integral The definite integral is a number… it is the area under the curve between x = a and x = b. Area below the x-axis is negative since the y-coordinates (the heights of the rectangles) are negative.
7
Definite Integrals If a function f is continuous on the interval [a,b], then… where F is any antiderivative of f.
