Nothing triggers mathematical PTSD quite like these abominations. Let's break down this parade of horrors:
• That natural log with the subscript e is redundant torture - it's like saying "ATM machine" but for people who actually passed calculus
• The square root of 2 with that tiny 2 on top? Pure sadism. Is it the square root or not? Make up your mind!
• Sin⁻¹(x) looking like a reciprocal when it's actually the inverse function. Thirty years teaching and I still have to remind students it's not 1/sin(x)
• And that x² = x×x monstrosity... I've failed students for less. Probably why my course evaluations are terrible.
No wonder mathematicians drink.
