Shapes Demo:

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

Start MathTrax and select "Equations".

Enter the following equations and sonify them.  Can you hear what shape they make? 

1.  r=cos(3*theta) - 3 bladed clover

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

3. r=1+cos(1.0*theta) - a sideways heart

Can you figure out how to make the heart right side up?
