For the method to work, the coefficient of the second derivative has to be unity. You have to start the calculation of the P.I. by dividing throughout by
I think I'm doing this right, but I'm not getting the right answer it seems.
Use variation of parameters to find a particular solution of the non-homogeneous Cauchy-Euler problem:
I found the roots to be 1,2 so my general solution is
Then I used variation of parameters. I found , the Wronskian of and , to be and and to be and respectively.
Dividing and by I get as and as
Integrating I get and
So my should be
Whenever I put this in, it says it's not correct. If there's something I'm missing or that I did incorrectly, any help would be appreciated.
