(a) find the riemann sum for f(x) = 4 sin(x), 0 ≤ x ≤ 3π/2, with six terms, taking the sample points to be right endpoints. (round your answers to six decimal places.)

Split up the integration interval into 6 subintervals:

where the right endpoints are given by

for . Then we approximate the integral

by the Riemann sum,

Compare to the actual value of the integral, which is exactly 4.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
