Polar Coordinates Calculator

Convert points between polar and Cartesian coordinates, or type r as a function of θ and watch the curve drawn on a polar grid.

What you can do

  • Convert between (r, θ) and (x, y), in radians or degrees
  • Exact surds at multiples of π/6 and π/4, with decimals beside them
  • Plot polar curves over any range of θ
  • Recognises circles, roses, cardioids, limaçons and spirals
  • Finds the area swept out by a curve
  • Practise conversions with worked solutions
