Looks ok to me. Assuming the initial differential equation is correct, it may be that the final expression is just a different transformation. My issacphysics keeps crashing, so can't confirm it, but try splitting up the exponentials, ... I'd try keeping all the terms in C together () multiplied by the f() term.
