Problem 1. Consider calculating the area under the function f(z) = = over [1.6). (a) Approximate the area wasing a right-hand sun and n = 5 rectangles. Support the calculation with a diagram. (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 s = 20 rectangles. Turn on both the RHS and LHS and include a screenshot
