Parkour Memes

The mathematical rebel we didn't know we needed! This is basically the calculus equivalent of taking the fire escape instead of the elevator. Integration by parts requires you to remember that whole u·dv = uv - ∫v·du formula and sometimes feels like you're just creating more problems for yourself. Meanwhile, substitution is like "new variable, who dis?" — just swap things out and cruise to the finish line. It's the mathematical equivalent of saying "I know there's a proper technique here, but I'm going to parkour my way through this problem because I refuse to follow your arbitrary integration rules!"
