how do you input cotangent into the calculator without using 1 / tan()?

Hi Guest #1,

I love your story though. Your story is like Harry Potter + Pokemon + Vampire videos + Star Wars LOL(Sorry for mentioning too much film names here.........) :D But here's the answer to this question.

Just use cot(angle) <-- This code would be good. :D

Input cot(45) and press enter: Output \(\mathtt{cot(45)=1}\)
