A very difficult, if not impossible, question often put on science and engineering tests to determine who is working with others and/or using Chegg, Symbolab, or other "help" websites. Works best on take-home exams. The OG move is for the professor to enlist a teaching assistant to post a convincing yet fake answer on one of these types of sites. Sometimes also referred to as "Chegg bait".
Billy: "How'd you do question number 3 on the differential equations exam?"
Bob: "I just used Symbolab."
Billy: "Damn, you just failed the cheat check! That integral is not solvable by methods we've learned."
