| 摘 要： | 将超越函数用其幂级数展开式的前n项和近似代替,将超越方程的求解转化为代数方程的求解问题,避免了很多复杂的数学计算.文章结合二分法基于VisulBasic6.0语言编写了求解代数方程的程序,其求解精确度远远高于用Mathmatica计算软件所计算的结果.

| Abstract: | Many complex mathematical calculation can be avoided by replacing transcendental function with the first several items and approximate value of the power series expansion,transforming the transcendental equation solution into algebraic equation solution.This paper introduces the program of algebait equation solution based on Visul Basic6.0 by combining the dichotomy.Its precision is much higher than the result calculated with Mathmatica. |

| Keywords: | dichotomy graphical solution transcendental function |
