Descartes found that the graphs of second-degree equations in two variables always fall into one of seven categories:

[1] single point, [2] pair of straight lines, [3] circle, [4] parabola, [5] ellipse, [6] hyperbola, and [7] no graph at all.

We shall first look at the four loci: circle, ellipse, hyperbola, and parabola, known as non-degenerate conic sections from a geometric perspectiv
