y' = x² + y² - r² (r = 0, 1, 2, ..., 7)

y' = (x + y)/(x - y) (method 1)

y' = (x + y)/(x - y) (method 2)

y' = sin(x)/y + sin(y)/x

y' = cos(x) + cos(y)

y' = cos(x) sqrt(1+x²) + cos(y) sqrt(1+y²)

Five Interlaced Crescents

Let A and B be two disks with radii a and b.

The set difference A\B is used to plot the moons

in the following animations.

Animation parameter: the position of B

Animation parameter: b (the radius of B)

Animation parameter: the position of A

Animation parameter: a (the radius of A)
