If you have not already done so, you should read section 6.4 in the textbook.

The practice problems for the quiz are here

The homework sheet is here note that there is a point missing on the worksheet; and I reccommend using this Mandelbrot/Julia set applet to do the homework (I find that this applet works best with Explorer). Michael just e-mailed to point out that I don't have a point that corresponds to #7. I will give 1 point extra credit to everyone who finds and draws in a point that will give #7.
