Sacred texts Memes

Every calculus student's fever dream! The post claims to have found the mythical "chain rule for integration" - which is basically like claiming you've spotted Bigfoot riding a unicorn. Integration by parts, substitution, partial fractions... we have those. But a simple chain rule for integration? That's why the meme shows someone clutching "the sacred texts" - because such a discovery would be the mathematical equivalent of finding the Holy Grail. Mathematicians have been crying into their coffee for centuries because the reverse chain rule isn't as elegant as its differentiation counterpart. Sorry to burst your bubble, but if you're still hunting for this mathematical unicorn, you might as well search for a proof that P=NP while you're at it.
