Three notes on Newton's iteration method for nonlinear equations
Three notes on Newton's iterative method for solving nonlinear equations are given.① For some equations,Newton's iteration method converges for any initial value.②For some equations,Newton's iteration method does not converge when the initial value is taken on a certain interval.③ For some equa-tions,iteration values of Newton's iteration method appear alternately,and Newton's iteration method does not converge.
