The Newton-Raphson Method
The Newton Method is used to find complex roots of polynomials and roots of systems of equations in several variables where the geometry is far less clear |
When we evaluate a monotone function f(a) in the interval [amin,amax], by building the sequence xn defined by the Newton-Raphson iteration, the natural choice consists in choosing x0 equal to the arithmetic mean of the endpoint values.
This minimizes the maximum possible distance between x0 and f(a).23 mai 2006
How do you choose initial guess in Newton-Raphson method?
The idea is to pick an initial guess x0 such that f(x0) is reasonably close to 0.
We then find the equation of the line tangent to y=f(x) at x=x0 and follow it back to the x axis at a new (and improved) guess x1.
The formula for this is x1=x0−f(x0)f′(x0).
How do you choose the starting point for the Newton method?
How To Use Newton's Method.
The idea behind is to start with an initial guess which is reasonably close to the true root (solution) and then to use the tangent line to obtain another x-intercept that is even better than our initial guess or starting point.
Why Newton-Raphson method is preferred?
The Newton Raphson Method is referred to as one of the most commonly used techniques for finding the roots of given equations.
It can be efficiently generalised to find solutions to a system of equations.
Moreover, we can show that when we approach the root, the method is quadratically convergent.
