Question: Approximate the indicated area by connecting succesive yvalues on the curve by a straight line, resulting in trapezoids. Use n = 4 trapezoids to estimate the area of the region in Exercise.
Exercise: Without using a spreadsheet, determine the approximate area of the region bounded by the given curve, the x-axis and between the given lines, using the indicated number n of rectangles.
F(x) = x2 between x = 4 and x = 5,n = 4 using the
(a) left endpoint,
(b) right endpoint,
(c) midpoint
