Question

How do you graph `r=1`?

Answer 1

The cartesian form is `x^2+y^2=1`, representing unit circle, with center at the origin.

Explanation:

The locus of the point that is always at the same distance from

another point is a circle. Here, the distance r =1. is the distance from

r = 0, representing the pole in polar coordinates., Graph is obtained,

using `r = sqrt(x^2+y^2)`

graph{x^2+y^2-1=0 [-10, 10, -5, 5]}
