The sender chooses between two. Circle on a Graph. Cartesian Equations and Polar Equations When we want to reference points in a plane with both Cartesian coordinates and polar coordinates, we superimpose the planes so that the polar axis coincides with the positive direction of the x-axis, and the pole corresponds to the origin.This allows us to more easily rewrite a Cartesian equation as a polar equation and vice versa.

Therefore the graph of the equation is symmetric about both the x-axis and the y-axis. Ellipse x ^2 / a ^2 + y ^2 / b ^2 = 1:. Le equazioni x^2+y^2=1 e x^2-y^2=1 sono due equazioni di secondo grado nelle due incognite x ed y, ed ammettono rispettivamente infinite soluzioni date da:.
