3.10 I: Numerical methods

 
Content
I1

Locate roots of

fx
= 0 by considering changes of sign of
fx
in an interval of
x
on which
fx
is sufficiently well-behaved.

Understand how change of sign methods can fail.

 
Content
I2

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

Solve equations using the Newton-Raphson method and other recurrence relations of the form

xn+1=g(xn)

Understand how such methods can fail.

 
Content
I3

Understand and use numerical integration of functions, including the use of the trapezium rule and estimating the approximate area under a curve and limits that it must lie between.

 
Content
I4

Use numerical methods to solve problems in context.
