To expand on the question, I recently (as in yesterday) posted a question on Math.SE and also wrote my answer in the post, claiming that my answer was wrong. One answerer pointed out that I was correct, but simply needed to do a quick deduction step, after which I edited that question with that deduction step.
So if I use this answer now in my assignment, will it be considered an academic offense? None of my university's resources are helpful at all in this regard. I'm a student in the sciences, and all the 'resources' of the university are towards arts students. I'd like a clear cut answer because informing my instructor that I posted my own interpretation of a question on an assignment is really out of the question, since I don't know if consequences exist for that.
I'm already looking for an alternative answer, but I'd like to know if using my current answer would be an academic offense. Thanks.
