"WitrynaNewton’s Method We wish to nd x that makes f equal to the zero vectors, so let’s choose x 1 so that f(x 0) + Df(x 0)(x 1 x 0) = 0: Since Df(x 0) is a square matrix, we can solve this equation by x 1 = x 0 (Df(x 0)) 1f(x 0); provided that the inverse exists. The formula is the vector equivalent of the Newton’s method formula we learned before. " - Newton method for nonlinear equations
