Week 8: October 19 - 23

Convergence of Root-Finding Methods

We continue our study of root-finding methods, examining the speed with which different methods converge to a solution.

Complex Numbers

Complex numbers are introduced as pairs of real numbers that obey certain rules for addition and multiplication. It is shown that this naturally leads to a geometric view of complex numbers, and that Newton's method can be applied equally well to find the complex roots of polynomial equations.


NumPy arrays can be used to represent both color and grayscale images. We learn how colors are represented in terms of red, green, and blue components, and some of the functions Matplotlib provides for saving, loading and displaying images.
