(Julia set) The preceding exercise describes Mandelbrot sets. The Mandelbrot set consists of the complex c value such that the sequence is bounded with z₀ fixed and c varying. If we fix c and vary the point (x, y) is said to be in a Julia set for a fixed complex value c, if the function stays bounded. Revise Exercise 15.20 to draw a Julia set as shown in Figure 15.13b. Note that you only need to revise the count method by using a fixed c value(-?0.3 + 0.6i).
