The curves intersect at (l, 8) and (2, 1). Use integration to find the exact area ofthe shaded region enclosed between the two curves. [7] The diagram shows the curve y = 4x—3 and the normal to the curve at the point (7, 5). The shaded region is bounded by the curve, the normal and the x-axis. Find the exact area of the shaded region. [8]

Example 1 Find the area enclosed by 2−x2 and −x. Solution The first consideration we need to make is to find where the two curves intersect, so that we can determine which regions are enclosed by the two functions. To do so we set the two functions equal, and solve. 2−x2 = −x x2 −x−2 = 0 (x+1)(x−2) = 0 So the region of interest ...
