Numerical Methods Locating Roots, Iterative and Newton-Raphson - A level A2 Mathematics

These PowerPoints form full lessons of work that together cover the new A level Maths course for all exam boards. Together all the PowerPoints include;
A complete set of notes for students
Model examples
Probing questions to test understanding
Class questions including answers
Individual whiteboard work
Links to exercises in ‘The Textbook by CGP’ these can easily be edited for your textbook
The PowerPoints can be used in the lesson and also given to students that have missed a lesson
I have added ‘A2 level maths 13 - Composite functions’ for free download
Please leave a review as it will really help me to improve my resources

Numerical methods locating roots and Newton-Raphson covers;

• Locate roots of f(x)= 0 by considering changes of sign of f(x) in an interval of x on which f(x) is sufficiently well-behaved
• Understand how change of sign methods can fail
• 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 x_(n+1) = g(x_n )
• Understand how such methods can fail
• Use numerical methods to solve problems in context
