Webtangent to cubic 8/16/2007 2 The algebraic analysis The family of lines through the origin is described by the equation y = mx where m is the slope of the line. To get hold of the intersections, we equate the y-values: x2(6–x) = mx. Now we want exactly two intersections, so we want the value WebFor a cubic to be 'curvy', there should be two stationary points, so the gradient function (i.e. the quadratic) must have two reals solutions when set to equal zero. Therefore the discriminant () must be positive so. To generate an 'uncurvy' cubic there should be no stationary points, so the gradient function must have no solutions when set to ...
