    This is a support page for Polar Graphing. Here is review material and polar graph paper. Below are links for further research, and some suggested tasks/questions.



    Cardioid is Greek for "heart."

  • Use the formulas at the left and Polar Graphing to seek why it has this name.
  • Use the link just above and make your own cardioid.
  • Feel lazy or want a hink of the possibilities, see bPolarLibrary and dPolarLibrary.
  • Do some research to see what a Wankle engine has to do with a cardioid.
  • Check out Cardioid at Wikipedia.


    Limacon is Latin for snail.

  • Visit Limacon at History at St. Andrews.
  • See: Limašon trisectrix -- angle trisection at Wikipedia.
  • Take the equation at the left an see if you can generate a similar curve you like better.


    Lemniscatus is Latin for "decorated with ribbons" and these look like a figure 8.

    See Lemniscate at Wikipedia.
