Section 6.3

I'm not too sure if I see the whole point behind fixed-point iteration. Where would this algorithm be applicable. I thought it was really easy to understand the check for contraction. I understand the concept behind the fixed point iteration and I find it interesting that we are using the concepts of root-finding to do the fixed-point iterations. I'm not exactly sure if I believe all the math yet but I'm sure with looking at it more closely that won't be a problem.
