摘 要: | 对于线性非齐次微分方程L(y)=f(x),当函数,(x)=ame^ms+am-1e(m-1)x+…+a2e^2x+a1e^x+a0(m为整数,ai为常数,i=1,2,……,m)时,可通过自变量变换e^x=t,将线性非齐次微分方程L(y)=f(x)化为方程L(y)=amt^m+am-1t^m-1+…+a2t^2+a1t+a0直接求其特解。

Abstract: | Take off to want: To the line not together time distance L (y) = f( x ) with square differential calculus, be the function (x)=ame^ms+am-1e(m-1)x+…+a2e^2x+a1e^x+a0(the m is an integral, the ai is a constant, i = 1,2, …, m), from change the quantity transformatione" = t,line not together time the distance L (y) = f( x ) with square differential calculus change into square distance L(y)=amt^m+am-1t^m-1+…+a2t^2+a1t+a0, begging it directly to solve especially. |
