Finding the Area Under a Curve In this task, you will practice nding the area under a nonlinear function by using rectanglrits2 You will use graphing skills in addition to the knowledge gathered in this unit. Sketch the graph of the functiony = 20x , and approximate the area under the curve in the interval [0, 20] by dividing the area into the given numbers of rectangles. PartA Use ve rectangles to approximate the area under the curve. Characters used: 0 115000 Part B Use 10 rectangles to approximate the area under the curve. Characters used: 0 2' 15000 Part C Calculate the area under the curve using rectangles as their number becomes arbitrarily large (tends to innity). You do not need to sketch the rectangles. Characters used: 0 115000
