How to converting equations in polar coordinates into equations in rectangular coordinates

We know now how to convert polar coordinate points (r,theta) into rectangular coordinate points (x,y). We’ve used the conversion formulas x=rcos(theta), y=rsin(theta), r^2=x^2+y^2, and tan(theta)=y/x. In the same way that we used these conversion formulas to convert coordinate points, we can also use them to convert equations from polar coordinates into rectangular coordinates.

How to convert polar equations into rectangular equations

To convert polar equations to rectangular equations, we’ll use the conversion formulas x=rcos(theta), y=rsin(theta), and r^2=x^2+y^2. Our goal will be to replace all the r and theta variables with x and y variables.
