The pure joy of discovering derivative shortcuts is captured perfectly in this Toy Story meme! Before learning derivative rules, calculus students are stuck with that terrifying limit definition - manually calculating each derivative like some kind of mathematical torture. Then suddenly, power rule, chain rule, product rule enter the chat and it's "See ya never!" to that limit nightmare. Students literally toss that complicated formula aside like Woody dismissing a toy that's no longer needed. The mathematical glow-up is real - going from spending 20 minutes on one problem to knocking out derivatives in seconds. Freedom never felt so good!
