Frequently Asked Questions
What are polar coordinates?
Polar coordinates represent a point by its distance from the origin (r) and the angle (θ) measured counter-clockwise from the positive x-axis. They are an alternative to the rectangular (Cartesian) system (x, y). Conversion: x = r·cos(θ), y = r·sin(θ).
