Ordinary Differential Equation questions....

[dkamis]

Okay, i went to see a tutor today and i worked out most of the problems we had time for, but i could not get to these 3 problems and i have no idea how to start them.

1. Given the solution y1(x)=x of the homogeneous equation, find a general solution of the differenetial equation

(x^2 - 1)y'' - 2xy' + 2y = 2 on the interval -1<0<1



2. Find all the solutions of the given system of equations

x' = (1 -3) ( 2 )
(3 y)X + (-10)


3. Solve y'=2*y + 5x^(4)*e^(2x), y(0)=0

Jolly is very right. In order for us to help you, you must provide the steps that you have taken already to complete this assignment. We can not get you UNstuck if we do not know where you are STUCK. Having said this please repost with what you have done thus far. Thank you!

Hey, Lizzie, glad to see you follow my motto of "No work shown, no help given!". :wink:

Well, I do know that if you don't try the steps yourself, you won't learn anything. That's why I have gotten into the habit of posting my problem, what I've done so far, where I'm stuck or what I don't understand and then that I would appreciate just a "push in the right direction" and then I let it be known that I am not looking for the answer, just help getting to it. This way you can learn what you're doing and you dont get behind in class.
