此类方程被称作齐次线性方程(homogeneous linear equation). 故二阶齐次线性微分方程的形式为 P(x)d2ydx2+Q(x)dydx+R(x)y=0 . 若对某些 x, G(x)≠0 ,则此时的微分方程为非齐次(nonhomogeneous)的,关于此类方程的求解参见17.2节. 如下两个基本定理为解齐次线性方程的基础: ★ 若y1(x) 和y2(x) 均...
Hairer and Wanner, 1976, have considered obtaining Nystrom type methods for the general second order differential equations and they listed order conditions for the determination of the parameters of the method. For the integration of special second order differential equation, order conditions was ...

叔的饼上回烤了一半,今天接着烤。今天解决的是:second order differential equations,二阶微分方程。这回就难一些了。为毛呢?这还用叔说么,你烤两层的饼,肯定要比烤一层的饼费一番功夫了!这还用叔说,真是的,没吃过饼,还没看过...
We can solve a second order differential equation of the type: d2ydx2 + P(x)dydx + Q(x)y = f(x) where P(x), Q(x) and f(x) are functions of x, by using: Undetermined Coefficients which only works when f(x) is a polynomial, exponential, sine, cosine or a linear combination...
