Fixed point iteration Sunday
Spent the morning trying to figure out how to teach fixed point iteration in particular the rearranging the equation method. Trying to teach something really makes you learn it thoroughly. I thought I understood it until I tried to create a lesson plan trying to explain the method. I think I have satisfactory answers for most of the but why questions that might come up. Is there a better way of describing why the gradient effects diverging/converging apart from showing staircase/cobweb on the graph? Do others teach Newton-Rhapson first? Think I'm going to have to work every sunday to keep on top of this A level content this year.
