SUMMARY
The discussion centers around solving the differential equation y'' - y = cosh(x). The user, Sparky_, questions the accuracy of the answer provided in the back of a textbook, specifically regarding a term with a coefficient of 1/8 on e^x. Another participant clarifies that this term is part of the solution to the homogeneous equation y'' - y = 0 and can be incorporated into the general solution as c1*exp(x) + c2*exp(-x).
