标 题: 解方程x=sin(x)

解析解方程:
x=A*sin(B*x+C). A,B,C已知。
结果最好能表示成 sin(n*C)的级数。不行也可以,给个近似的解,也行,但是就是要
解析。
请问怎么做?
多谢。 | g*****g 发帖数: 390 | 2 I don't think there is an analytical solution for this. I kind of remember
this equation, either for high school or college. Back then, it was a
selection problem, so you can use chart to find approximate answer. |
