Newtons method in the complex plane



Times and Place

Tuesday 10th October 12:30-14:00 in 5A
Wednesday 11th October 14:30-16:00 in 5G

Wednesday 11th October 16:30-18:00 in 25.42 2542.00.41 and
Thursday 12th October 14:30-16:00 in 25.42 2542.00.41


This short course mainly is about bringing students together with mathematical beauty of fractals. You will learn about fractals, Mandelbrot sets and Julia sets. In the computer lab sessions we will develope basin portraits of polynomials.
