Newton's method - Wikipedia
https://en.wikipedia.org/wiki/Newton's_methodNewton's method can be used to find a minimum or maximum of a function f(x). The derivative is zero at a minimum or maximum, so local minima and maxima can be found by applying Newton's method to the derivative. The iteration becomes: An important application is Newton–Raphson division, which can be used to quickly find the reciprocalof a number a, using only multiplication and subtraction, that is to say the number x su…
APPLICATION OF THE NEWTON-RAPHSON
www.vibrationdata.com › tutorials_alt › newrapThe Newton-Raphson method is a method for finding the roots of equations. It is particularly useful for transcendental equations, composed of mixed trigonometric and hyperbolic terms. Such equations occur in vibration analysis. An example is the calculation of natural frequencies of continuous structures, such as beams and plates.
