Why not substitute D and S into the equation for ?

This will give you a second order constand coefficient ODE. - February 20th 2010, 09:16 PMIBD

My dearest Prove It can you please send me a pm with some contact information (email)? I cannot send you a pm because I am a new member and don't have 15 posts. I need to discuss something in private. Thanks
