Conversion Formulas

Cartesian to Polar

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

theta = atan2(y, x)

Polar to Cartesian

x = r x cos(theta)

y = r x sin(theta)

Understanding Coordinate Systems

Cartesian Coordinates

Uses perpendicular x and y axes to specify a point's location by its horizontal and vertical distances from the origin.

Polar Coordinates

Uses distance from origin (r) and angle from positive x-axis (theta) to specify a point's location.
