## Question:

Find a polar equation of the form {eq}r = f(\theta) {/eq} for the curve represented by the Cartesian equation {eq}x^2 + y^2 = 2cx {/eq}.

## Polar Coordinates:

We have the Cartesian equation of a circle in the xy-plane centered at point ( *c* , 0 ) and with the radius |*c*|.

We find the polar equation of this circle by using the equations for the cartesian coordinates in terms of polar coordinates.
