The classic five pointed star

r = cos(k*theta), k = 3 in this example

After using a compass to draw a circle this is often drawn next

The Utah Teapot rendered in wire frame with hidden lines removed

A tractrix curve rotated in three dimensions rendered in wire frame with hidden lines removed

This aquiline shape is made of five arcs and a circle and this one is made of three arcs and a circle

x = 8 cos(theta) - 6 cos(8 theta/3), y = 8 sin(theta) - 6 sin(8 theta/3)

A hypotrochoid: x = 2 cos(theta) + 5 cos(2 theta/3), y = 2 sin(theta) - 5 sin(2 theta/3)

The Butterfly Curve: r = exp(sin(theta)) - 2 cos(4 theta) + (sin((2 theta - pi)/24))^5

r = 3 sin(0.8 theta)

x = 2 sin(2 theta), y = 2 cos(3 theta)

A parametric heart: x = 16 sin(theta)^3, y = 13 cos(theta) - 5 cos(2 theta) - 2 cos(3 theta) - cos(4 theta)

x = 13 cos(theta) - 5 cos(2.6 theta), y = 13 sin(theta) - 5 sin(2.6 theta)
