Thanks for looking into my problem Prove It. I have inserted a picture of the exercise but it seems that you could not see it. I have now uploaded it as an attachment. Thanks again
Thanks Prove it for your response. I will substitute into p'' however i don't get p' this way. could you please let me know how i will obtain the differential equation that the first question asks for?

You should end up with
.
So .
Solve the homogeneous characteristic equation:
.
Now since and , this means .
Also, since , this means .
So you have equaling a negative number. What does this tell you about ? Can you solve the DE now?
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
