I'm supposed to do the integral (e^x)(sinh x) by integration by parts. I'm guessing I'm supposed to do it over again until I get the negative expression of the first integral on the right side, then add it to both sides and divide the right side by 2. However, I can't seem to get the expression "negative" on the right side...
Another way to do it, would of course be to use the definition of sinh x directly. This I tried to do (attachment), but I'm still not sure if I got the right answer.
Any help? Thanks!
... which, granted, means looking inside sinh and ignoring a much simpler way, but nonetheless...
... where (key in spoiler) ...
(And solve the top row for I.)
