用二分法求解非线性方程,只要用户输入所求的方程,方程的根就很快被程序计算出,方便而且还很快捷.对于数值分析这样的课程,将算法通过程序实现,具有很好的教学价值.-dichotomy used to solve nonlinear equations, as long as import demand equation, the equation roots soon be worked out procedures to facilitate and very fast. Numerical analysis for such courses, the algorithm can be achieved through the process, with very good teaching value.
