  • 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.
