OK, what you want to do is first solve for y', givingyou: y' + (2/t)y = (sin t) / t Then let some function mu(t) be a function of t and multiplyboth sides by mu(t), giving us: mu(t)*y' + mu(t)*(2/t)y = mu(t)*(sin t)/t Use an equation from your book (hint), to solve for mu(t), andyou should get that mu(t) = t^2 for the specific case. Nowjust plug mu(t) in, integrate both sides, and solve like anordinary differential equation. Hope this gets you going on the right track!
