Shapes Demo

Some equations make cool shapes.  Can you come up with a novel shape?  Email us your shape equation.

The equation that made this shape is:

r=sin(2*theta)

Try these easy shapes :

r=cos(3*theta) - 3 bladed clover

r^2=8.0^2*cos(2*theta) - a figure 8

r=1+cos(1.0*theta) - a sideways heart...Can you figure out how to turn it right side up?
