Solving a Cubic via the Trisection of an Angle
Solving a Cubic via the Trisection of an Angle
This Demonstration shows a geometric solution to the equation +px+q=0, where and are real in the case where the equation has three distinct real roots (i.e. has a positive discriminant). It is based on Viète's trigonometric solution of the cubic that constructs and trisects a particular angle associated with the given cubic equation.
