That almost makes sense, but pi radians = 180°
Right, a triangle “has 180deg,” like I said.
in which case π÷n is infinitesimally small. In other words, substituting infinity for n would be incalculable
That’s not how limits work. Substitution is not the same as taking the limit.
infinite and infinitesimal numbers are impossible to express rationally.
That’s not true at all. https://en.wikipedia.org/wiki/1/2_%2B_1/4_%2B_1/8_%2B_1/16_%2B_⋯
It’s not about colloquialism or language
Having one word (or phrase) with two meanings is a property of language.




I feel like people who don’t like salads really just don’t like salad dressing (and vice versa, I guess).
Smother those salads in a simple red wine vinegar and Dijon + EVOO dressing and I’d be plenty happy.
