differential equation help
OK. I'm working on a homework problem in Diffy Equ. and I'm stuck halfway through. It is a homogenius equation w/ constant coefficients.
y(0)=-7, y'(0)=7, y''(0)=-7
I've gotten as far as:
I'm getting stuck on solving for c1 c2 and c3 which I guess is more algebra than anything. If someone could walk me this it would be great. I was using substitution. After I get this I can do the rest.
