Quick Summary

A cubic curve is a mathematical concept defined by a polynomial equation where the highest sum of the variables' exponents is three. This can manifest as a cubic equation, a cubic surface, or a twisted cubic space curve. In analytic geometry, cubic curves are studied by representing them with algebraic equations. For instance, Isaac Newton demonstrated that all plane cubics can be represented by one of four standard equations. A cubic surface is specifically defined as an algebraic surface where any plane intersecting it results in a cubic curve.12345

…described by cubic equations; a cubic curve is determined by four points or, equivalently, by two points and the curve’s slopes at those points. Two cubic curves can be smoothly joined by giving them the same slope at the junction. Bezier curves, and related curves known as B-splines, were introduced…
