Polar Function Grapher

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)
r =                   θ goes from to (in radians)
r =                   Animate drawing

  • This applet graphs the polar function r = f(θ).
  • Use t instead of θ in the input box above as you define functions (it's easier to type!)
  • The following functions are allowed: abs( ), sqrt( ), cbrt( ), exp( ), ln( ), log( ), cos( ), sin( ), tan( ), cosh( ), sinh( ), tanh( )
  • Ctrl + [click and drag] on the background to move the coordinate axes around.
  • Ctrl + [scroll wheel] to zoom in and out.
