The problem is: Solve : y'' y = cosh(x)
I've attempted a solution and is attached.
The answer in the back of the book agree with part of mine. However, the circled part  the part with 1/8 as a coefficient on e^x terms. It's circled on the bottom.
Either the back of the book is wrong (and I'm correct) or this term should cancel and I've missed something.
Help?
Thanks
