Look at this shmuck, using the supremum of a continuous function on a closed interval when it clearly achieves a maximum. I bet they’ll feel real embarrassed about that one when they’re falling asleep years from now.

I get you are joking, but I’ve seen many literature just using sup for maximum. Maybe for consistency or laziness, idk why
