When does iterating z -> z^2 + c have an exact solution?
up vote 38 down vote favorite
If one iterates the map z -> z^2 + c there is obviously a simple formula for the sequence one gets if c=0. Less obviously, there is also a simple formula when c = -2 (use the identity 2 cos(2x) =
(2cos(x))^2 - 2).

This is a little experiment to create the effect of an endless series of objects flying towards the viewer.
The objects are tweened in time. All variables are based on a ratio r that goes from 0 to 1.
An easing equation is used on r, after it is computed, to slow it down at the beginning and ends.

Groups of linear transformations
Finite-dimensional linear transformations are used a lot in theoretical physics. They form a group with respect to multiplication, and some of these groups are extremely useful. So we are dealing
with matrix products.
