Yeh that's what i meant. Awsome, cheers for the help! thought it was something like that

Homework Statement The problem is not getting the answer to the laplace transform but instead reducing my answer so i dnt lose marks. If i work out the laplace transform of: L(t^3 * sinh(4t)) to be 3!/(2(s- 4)^4)- 3!/(s(s+ 4)^4) then how do i add these to get a single fraction? Its doing...

We were given the solution y(1) = x^2 was a solution, then had to prove y(2) = log(x)x^2 is also a solution. Haha your spot on about me getting y(p) via constant coefficients, which i ended up realising just before and ajusted my solution. Seems so stupid now i look back at it. I did end...

Ok here's my problem: 1. Solve the inhomogeneous second order de: x^2y" - 3xy' + 4y =x^4 2. Worked: y(p) = 1/4*x^4 Given: y(1) = x^2 y(2) = log(x)*x^2 3. I just need help getting the roots of the given de so i can determine y(h) of this de. As...

So obvious now you have pointed that out. Im all over it like a bad rash now Thanks heaps

Hey guys just asking for a bit of help to get me on the right track. I have the non homogeneous de 4y" + 4y' + y = 3*x*e^x, which also has some inital conditions y(0)=0 and y'(0)=0. but i only need help with getting the particular solution. Tried method of constant coefficients and it...
