@Xam Thanks! The reason I ping you is that you are capable of judging the mathematical correctness of the post and you can downvote if you wish. Users who have 10k reputation cannot even vote to delete an answer unless it has negative score, so our hands are tied when it has too many upvotes.
@SimplyBeautifulArt Sorry, really wanted to answer it. Though the OP has now included a graph of the equation, so maybe worth not closing. Anyways, do as you wish.
