Math Problem Statement
Unless specified, all approximating rectangles are assumed to have the same width. Evaluate the upper and lower sums for f(x) = 2 + sin(x),
0 ≤ x ≤ 𝜋 with n = 2, 4, and 8. (Round your answers to two decimal places.) The x y-coordinate plane is given. A curve and two sets of 5 rectangles are graphed. The x-axis from x = a to x = b is divided into 5 subregions, each of which becomes a shared base for rectangles of width (b − a)/5. The curve enters the window in the first quadrant above x = a, goes down and right, changes direction, goes up and right, changes direction, goes down and right, and exits the window in the first quadrant above x = b. The first set of 5 rectangles extends up and intersects the curve at the higher value within each subregion. The second set of 5 rectangles extends up and intersects the curve at the lower value within each subregion.
