i have the first solution y_1(t) = t for (1t)y'' + ty'  y = 0.
I need to get the 2nd linearly independent using Abels theorem. the integration is messy but i have it set up (sorry no latex); y_2 = (t) * integral to t ( 1/s^2 * exp( integral to t (s(s+1) ds) ) ds. Could anyone show me how to do this integration step by step? Thanks in advance!

found it, integral was a telescoping series from parts. the solution is \exp(t)

Obviously, the second solution is exp(t)
