本文主要是介绍非线性方程的数值解法，通过对牛顿迭代法、二分法和弦截法的实例化求解，分析并得出其一般性适用情况。由于非线性方程在科学计算中的广泛应用，使其对处理科学、工程问题以及相关的数值计算问题具有一定的启发意义。%This paper mainly introduced the solutions of nonlinear equations,which was based on instantiation about the Newton iteration method,the dichotomy and the string method. And the general conclusion was given. Because it was widely used in scientific calculation,the nonlinear equation had inspirational value in dealing with science engineering problems and the numerical calculation promblems.
