# Constant Coordinate Curves for Parabolic and Polar Coordinates

Constant Coordinate Curves for Parabolic and Polar Coordinates

This Demonstration shows curves of constant coordinate values for the parabolic and polar coordinate systems in two dimensions. As you drag the locator in the plane, the curves are redrawn so they pass through that point. Holding the mouse over the curve shows which variable is constant along that curve, and holding it over the point gives the actual values of the variables. For comparison, the Cartesian coordinate system is also included.
