摘要
当求解含有三角函数的方程或方程组时,方程中的三角函数会增加求解过程的复杂性和难度。针对牛顿迭代法等常用求解方法中存在的问题,提出在计算机辅助绘制各方程对应曲线的基础上,利用方程中各参数之间的对应关系作辅助线,快速、简便地求解方程。并以AutoCAD 2005为平台,VBA为开发工具,通过计算实例对该方法的可行性和准确性进行了验证。
It is complicated to solve equation or equation set when it contains trigonometric function. In order to overcome the drawback of Newton iteration method, a new method is provided. The method is based on computer aided drawing corresponding curve of each equation and takes advantage of relations of parameters to solve equation. Compared with the common method, the new method is faster and simple. Utilizing VBA with AutoCAD 2005, an example is given to verify the feasibility and accuracy of the method.
