Function sequence , with ten cycle sequence
Now we have a sequence of functions rather than a sequence of numbers. This is an easy generalization. Many of the previous post could have been described as a function sequence with
In this case the sequence is a repeating ten-cycle of affine transformations (). The ten functions are pulled randomly, with replacement, from a set of three.
Since everything is linear here, no squares, no trig functions, the straight lines are expected.
