(a) Use implicit differentiation to show that y – 2x = 0 at P and at Q. (6) (b) Find the coordinates of P and Q. (3) June 2008 5. Figure 3. Figure 3 shows a sketch of the curve with equation y = , 0 ( x ( . The finite region R, shown shaded in Figure 3, is bounded by the curve and the x-axis. ................
