Two-Variable Function Pump
Exploration Questions
To understand the Mandelbrot set, we need to work with two-variable
(complex) functions.
- Practice your complex arithmetic by performing the following
operations:
- (0,-1) + (1/2,1/3)
- (.8,-.2) + (.1,-.3)
- (0,1)^2
- (.8,-.3)^2
- (1,.2)^2 + (-.2,.5)
- (.5,.5)^2 + (.5,.5)
- Iterate the function: f(Z) = Z^2 with the starting points
(0,0), (1,0), (.5,.5), and (1,1). Calculate enough iterations
for each to tell if it is a prisoner, escapee or neither.
- Try more starting points with f(Z) = Z^2. Can you guess
what the prisoner set looks like?
- Explore the function f(Z) = Z^2 + (.5,.5) by choosing 10
starting values. Record your results. Can you find any prisoners?
- Experiment with other C values, checking at least 5 starting
points for each, and record your results.
