Witryna3 The Newton Raphson Algorithm for Finding the Max-imum of a Function of k Variables 3.1 Taylor Series Approximations in k Dimensions Consider a function f : Rk →R that is at least twice continuously differentiable. Suppose x ∈Rk and h ∈Rk. Then the first order Taylor approximation to f at x is given by f(x+h) ≈f(x)+∇f(x)0h WitrynaGeometrical Interpretation of Newton Raphson Formula. The geometric meaning of Newton’s Raphson method is that a tangent is drawn at the point [x 0, f(x 0)] to the curve y = f(x).. It cuts the x-axis at x 1, which will be a better approximation of the root.Now, drawing another tangent at [x 1, f(x 1)], which cuts the x-axis at x 2, which is …

WitrynaA possible algorithm to find all roots of the polynomial P consists in: Start from some X0 and find a root R, using Newton's algorithm. Divide P by (X-R): the division is exact (up to numerical error) since R is a root. (this step is called deflation) Restart from the beginning if the quotient has degree > 1.
