A Puzzle for You, from the Heidelberg Integration Bee 2026

I submitted another integral to the Heidelberg Integration Bee this year, figured I'd share it here in case you want to give it a try! :) It uses a trick popularized by a famous physicist. Thanks to everyone who organized and participated in the Heidelberg Integration Bee 2026! It's a great event. You can watch the whole event here:    • Heidelberg Integration Bee 2026
