A cubic curve has equation y x3 3x2 1. (i) Use calculus to find the coordinates of the turning points on this curve. Determine the nature of these turning points.

y′=3x2 −6x use of y′ = 0 0= 3x^2 - 6x 0= 3x(x-2) therefore either x=0 or x=2 when x=0 y=1, when x=2 y=-3 (0, 1) or (2, −3) y''=6x-6 when x=0 y''=6(0)-6 = -6 as y'' is negative this means at x=o the curve is ...
