Initial Point The initial point of a parametric curve is the point which represents the x and y values when the parameter takes on the lowest value in its domain. (a) y = x 3 In standard form, the equation is x y = 3, so a = 1, b = 1, and c = 3. Cycloid Curve Written by Paul Bourke June 1997 Everyone has witnessed a rolling wheel or tyre, have you ever stopped to wonder what curve is traced out by a point on the rim of the wheel? Such a curve is called a cycloid. The point-roulettes for which a circle rolls on a line or on another circle, are known as cycloidal curves.
