20.09.2020 · The algorithm for Newton's Method is simple and easy-to-use. It uses the the first derivative of a function and is based on the basic Calculus concept that the derivative of a function $ f $ at $x=c$ is the slope of the line tangent to the graph of $y=f(x)$ at the point $ (c, f(c)) $. Let's carefully construct Newton's Method.

30.03.2016 · When using Newton’s method, each approximation after the initial guess is defined in terms of the previous approximation by using the same formula. In particular, by defining the function we can rewrite (Figure) as This type of process, where each is defined in terms of by repeating the same function, is an example of an iterative process .

Newton's method formula is given by Newton to calculate the roots of a polynomial equation by the iterations from one root to another. Calculating the roots by this method is a lengthy process for the higher degree of a polynomial but for the smaller degree of polynomials, this method gives results very quickly and close to the actual roots of the equation.

In calculus, Newton's method is an iterative method for finding the roots of a differentiable function F, which are solutions to the equation F (x) = 0. As such, Newton's method can be applied to the derivative f ′ of a twice-differentiable function f to find the roots of the derivative (solutions to f ′(x) = 0), also known as the critical pointsof f. These solutions may be minima, maxima, or saddle point…

The formula for Newton’s method is given as, x1 = x0 − f (x0) f ′(x0) x 1 = x 0 − f ( x 0) f ′ ( x 0) Where, f ($x_ {0}$) is a function at $x_ {0}$, f' ($x_ {0}$) is the first derivative of the function at $x_ {0}$, $x_ {0}$ is the initial value.

Given xn, define. x n + 1 = x n − f ( x n ) f ′ ( x n ) , {\displaystyle x_ {n+1}=x_ {n}- {\frac {f (x_ {n})} {f' (x_ {n})}},} which is just Newton's method as before. Then define. z n + 1 = z n − f ( z n ) f ′ ( x n ) , {\displaystyle z_ {n+1}=z_ {n}- {\frac {f (z_ {n})} {f' (x_ {n})}},}

Consider the problem of finding the square root of a number a, that is to say the positive number x such that x = a. Newton's method is one of many methods of computing square roots. We can rephrase that as finding the zero of f(x) = x − a. We have f′(x) = 2x. For example, for finding the square root of 612 with an initial guess x0 = 10, the sequence given by Newton's method is:
