标题[理工] 两题变系数的题目(工数)
时间Mon Jun 1 22:01:52 2009
1.Please find the solution of ordinary differential equation
(x^2+1)y''-2xy'+2y=6(x^2+1)^2
Boundary condition y(x=0)=-1,y(x=1)=5
2.Given an ordinary differential equation as
d^2y dy
x------ + 2(x-1)------- +(x-2)y=0
dx^2 dx
If boundary condition is given as y(0)=y0,solve for y(x).
先谢谢大家罗，变系数实在没有头绪..
