Infinite Loop? Nah, We're So Close

The mathematical purgatory of integration by parts! This meme brilliantly illustrates the recursive nightmare that calculus students face when solving certain integrals. Just like our little miner who keeps digging tunnels only to end up back where he started, integration by parts can lead you through a labyrinth of substitutions that loop right back to your original problem. You think you're making progress with each substitution, but suddenly—BAM—you're staring at the same integral you started with. It's the mathematical equivalent of digging your way to China only to discover you've circled back to your own backyard. Every calculus student has experienced this special form of mathematical torture!
