Law of cotangents - Wikipedia
In trigonometry, the law of cotangents is a relationship among the lengths of the sides of a triangle and the cotangents of the halves of the three angles. [1][2]
Introduction to the Cotangent Function - Wolfram
The classical definition of the cotangent function for real arguments is: "the cotangent of an angle in a right‐angle triangle is the ratio of the length of the adjacent leg to the length to the opposite leg." This description of is valid for when the triangle is nondegenerate.

What 's the differece between $\\cot(x)$ and $\\arctan(x)$?
Yes. cot x cot x is the reciprocal, arctan x arctan x is the (principal) inverse, and arctan x = 1tan x arctan x = 1 tan x is incorrect. There is a mistake. And the main problem is the notation. If we have a function f f that is 1-1 then we can think of it's inverse function f−1 f − 1.
