Evaluate the Riemann sum for f(m) = 73:2 6 on the interval [1, 2] using the partition of three subintervals (of equal length), with the sample point 11- being the midpoint of the ith interval. See Example 1 page 225 for a similar example. Evaluate the Riemann sum for f(')) = $3 5:122 l 2:: + 8 on the interval [0, 5] using the partition of five subintervals (of equal length), with the sample point ii being the left end point of the 'i-th interval. See Example 2 page 225 for a similar example. Approximate f32(m l 3)dm via the Riemann sum. Use the partition of five subintervals (of equal length), with the sample point i,- being the right end point of the ith interval. See Example 3 page 228 for a similar example. Approximate S (2x2 - 8) da via the Riemann sum. Use the partition of four subintervals (of equal length), with the sample point ; being the middle point of the i-th interval. See Example 4 page 228 for a similar example
