A Cartesian equation is a mathematical expression that defines a curve or surface in a Cartesian coordinate system using variables $x$ and $y$. For example, the equation of a circle with radius $r$ centered at the origin is $x^2 + y^2 = r^2$.

To convert a Cartesian equation to a polar equation, use the transformations $x = r\cos(\theta)$ and $y = r\sin(\theta)$. Substitute these into the Cartesian equation to get its polar form.
