Newton-Raphson method

Newton-Raphson is a root-finding algorithm which produces successively better approximations to the roots of a real-valued function.

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. It uses the idea that a continuous and differentiable function can be approximated by a straight line tangent to it.
