How to Find the Initial Guess in Newton’s Method

Witryna23 lut 2024 · Using this strategy, we can identify the consecutive roots of an equation if we know any one of its roots. The formula for Newton’s method of finding the roots of a polynomial is as follows: where, x 0 is the initial value. f (x 0) is the function value at the initial value. f' (x 0) is the first derivative of the function value at initial value.
