What is the Newton method?
In numerical analysis, Newton's method is named after Isaac Newton and Joseph Raphson.
This method is to find successively better approximations to the roots (or zeroes) of a real-valued function.
The method starts with a function f defined over the real numbers x, the function's derivative f', and an initial guess. xWhat is the Newton-Raphson method?
The Newton-Raphson method begins with an initial estimate of the root, denoted x0≠xr, and uses the tangent of f(x) at x0 to improve on the estimate of the root.
In particular, the improvement, denoted x1, is obtained from determining where the line tangent to f(x) at x0 crosses the x-axis.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).

1) The Newton-Raphson Iteration
Since the true root is r, and h = r − x0, the number h measures how far the estimate x0 is from the truth. 0 = f(r) = f(x0 + h) ≈ f(x0) + hf (x0), and therefore, unless f (x0) is close to 0, h ≈ − f(x0) f (x0) .
It follows that r = x0 + h ≈ x0 − f(x0) f (x0) .
