Abstract: A method for finding roots of nonlinear equations on a closed interval generalizing Newton's method is proposed. The class of functions for which the proposed method is convergent, is determined. The rate of convergence is estimated and results of a numerical simulation are given.

Keywords: nonlinear equation, Newton's method for finding roots, concave support function, Lipschitz condition.
