Which is correct?
The order is irrelevant. If you're getting different answers it will be because of a mistake somewhere on your part. If you show all your working, that mistake might be spotted. By the way, an obvious error is use of brackets ( ) rather than mod | |.

Thus either case(***) works and
As mentioned in my first reply, | | modulus NOT ( ) brackets are required around what you're logging. Also, the arbitrary constant of integration needs to be included. Omitting either or both of these will result in marks being deducted.
