1 5.1 Estimating with Finite Sums There is no easy formula for â–¯nding the area of a region bounded by a curve. Our goal for today is to develop a method for approximating the area by covering the region with a collection of rectangles. Consider a region bounded by a graph of a function f(x) y fHxL a b x We can...
