The NewtonRaphson Method(NEW!!) ExamSolutions YouTube

Ariel Gershon , Edwin Yung , and Jimin Khim contributed. The Newton-Raphson method (also known as Newton's method) is a way to quickly find a good approximation for the root of a real-valued function f (x) = 0 f (x) = 0. It uses the idea that a continuous and differentiable function can be approximated by a straight line tangent to it.

The Newton-Raphson method. The Newton-Raphson method finds roots of equations in the form f (x) = 0. It can be used to find approximate solutions when an equation cannot be solved using the usual analytical methods. It works by finding the x-intercept of tangents to f (x) to get closer and closer to a root.

Newton-Raphson method. Usually this will be given to you, but if not then you need to consider the following two points: If the starting value, 0, is near a turning point then the method can converge on a root quite slowly, as the tangent line will be far from the -axis. If the starting value, 0, is at a turning point then the method will fail.
