Chapter Definite Integrals Obj: find area using definite integrals

Review Estimate the area using 4 subintervals between f(x)=x 3 and the x-axis from 0 to 2 using left and right sums.

Riemann Sum Left Sum Right Sum Midpoint Sum Trapezoidal Sum

Definite Integral If f is defined on the closed interval [a, b] and the limit exists, then If f is continuous on [a, b], then f is integrable on [a, b].

Area IF f is continuous and nonnegative on the closed interval [a, b], then the area bounded by f, the x-axis and the vertical lines a and b is Area =

Examples

Rules 1.If f is defined at x = a,. 2.If f is integrable on [a, b], then 3.If c is on [a, b], then
