Name this shape sometimes named for Bernoulli [ber-NOO-lee] that is used to represent infinity and looks like a figure eight.
The first constant named for this shape equals pi times Gauss' constant. This shape is the inverse curve of a hyperbola. One form of the equation for this shape is the square of the sum of the squares of the coordinates equals the difference of the squares of the coordinates. Its equation is easier to state in polar coordinates, where r squared is proportional to the cosine of two theta.
