The Calculus Professor's Pet Peeve

The Calculus Professor's Pet Peeve

Nothing triggers a calculus professor faster than canceling differentials like they're fractions. That equation showing dy/du · du/dx = dy/dx is mathematically correct but for entirely different reasons than "the du's cancel out." It's the chain rule in disguise, not some algebraic simplification. Professors everywhere clutch their chalk in horror when students cross out the differentials like they're solving for x in 8th grade algebra. Pure mathematical blasphemy.
