Problem 1. Consider calculating the area under the function f(x) = = over [1.6). (a) Approximate the area using a right-hand man and n = 5 rectangle. Support the calculation with a cdiagram. (b) Approximate the area using a left-hand sum and a = 5 rectangles. Support the calculation with a diagram. (c) Average the RHS and LHS to improve the approximation. (d) Using a Riemann Sum calculator software online, approximate the area using n = 20 rectangles. Turn on both the RHS and LHS and include a screenshot
