In practice, cubic curves are the ones most commonly used.

Newton had studied the cubic curves, in the general description of the real points into 'ovals'.

This is a broad family of rational cubic curves containing several well-known examples.

The real points of cubic curves were studied by Isaac Newton.

For example, there are many cubic curves that have no such point, when K is the rational number field.

The cubic curve with a cusp through 4 points.

In the plane, every elliptic curve is given by a cubic curve.

Since this is similar in shape to a cubic curve a cubic model has been popular with some authors.

A cubic curve is a compound curve passing through O.

Isaac Newton carried out a detailed study of all cubic curves, the general family to which these examples belong.
