Numerical solution using Fixed point iteration and Newton-Raphson methods

In computational mathematics, an iterative method is a mathematical procedure that uses an initial value to generate a sequence of improving approximate solutions for a class of problems, in which the n-th approximation is derived from the previous ones. Convergent fixed-point iterations are mathematically rigorous formalizations of iterative methods. • Newton's method is a root-finding algorithm for finding roots of a given differentiable function . Th… WebWhat is the linear approximation newton method of root finding? We get x 1, using fixed-point iteration, if we plug in x 1 again we get X 2. We substitute we get X 3, so we will repeat the process until the result of X obtained is the same for successive steps.
