A-Level Maths Edexcel (9MA0)

Solve equations approximately using simple iterative methods; be able to draw associated cobweb and staircase diagrams.

Understand that many mathematical problems cannot be solved analytically, but numerical methods permit solution to a required level of accuracy.

Use an iteration of the form $x_{n+1} = f(x_n)$ to find a root of the equation $x = f(x)$ and show understanding of the convergence in geometrical terms by drawing cobweb and staircase diagrams.
