The Euler gallery of images explores various recurrence relations trapped by circles and rings. Named for Leonhard Euler, Swiss mathematician in the 1700’s, famous for forming the identity , which has been called “the most beautiful mathematical formula ever”.
Euler 3 involves orbit traps of a ring and three lines perpindicular to the real and imaginary axes. Each image is a different view of the same fractal.
Recurrence relation trapped by two rings.
Euler #8 and #9
Leonhard Euler developed the Gamma function, which is used in the recurrence relation for #8 and #9.
