Newton Raphson Method - University of Surrey
personal.maths.surrey.ac.uk › st › Sform f(x) = 0, as we now demonstrate, is called the Newton Raphson method. It is guaranteed to converge if the initial guess x 0 is close enough, but it is hard to make a clear statement about what we mean by ‘close enough’ because this is highly problem specific. A sketch of the graph of f(x) can help us decide on an appropriate initial guess x
The Newton-Raphson Method
www.math.ubc.ca › ~anstee › math104The Newton-Raphson Method 1 Introduction The Newton-Raphson method, or Newton Method, is a powerful technique for solving equations numerically. Like so much of the di erential calculus, it is based on the simple idea of linear approximation. The Newton Method, properly used, usually homes in on a root with devastating e ciency.
