Starting value

Definition

The value supplied before the repeated process begins, usually written as $x_0$ .

Used by Edexcel

Specification A20 · Paper 1, Paper 2, Paper 3

The rearrangement and the starting value both matter: one rule may approach a root while another valid-looking rule moves away from it, oscillates or becomes impossible to evaluate.
Revise: Iterative Methods

1
Write the iteration rule, the stated starting value and enough successive values to show how the approximation develops.
