Question

DEFINE P-R EQUATION IN CARTESIAN FORM
​

Answer 1

A Cartesian equation is an equation in terms of x and y only. We do this by rearranging one of the equations for x or y, to make the subject, and then substituting this into the other equation.

p = r

= $\sqrt{x^{2} }+{r}^{2} = r$

Squaring both sides we will get

= x² + y² = r
