ok wow, I have racked my brain at on this for about 5 hours with and without a study group.
I cannot seem how to set up the initial part of finding the particular solution.
I had found one variable and one point which was c = 1/162 but couldnt find A, or B.
I tried using but got stock when plugging in the second derivative in and couldnt not find answer for the rest of the coefficients.
what am I doing wrong?
