The circle equation in polar coordinates is:

<h3>
How to change the coordinates of the circle equation?</h3>
Here we have the circle equation:

First, we expand it to:

Now we can rewrite it as:

Remember that:

Replacing that, we get:

That is the equation in polar form.
Now, because we can discard the solution r = 0, we can divide both sides by r to get:

To simplify it.
