I’m not really a fan of concerts, but last year, my sister and I went to a Trans-Siberian Orchestra concert and it was absolutely phenomenal.
Probably because the screws can’t be used!
I did that exact switch for the same reason and I have to say, it’s one of the best decisions I’ve made in my Linux history!
I belive that this may be what you're looking for: https://en.wikipedia.org/wiki/Trigonometric_functions#Right-angled_triangle_definitions
The parameter for the sin function is an angle. The angle can be specified in either radians or degrees, depending on the context. The output of the sin function is the ratio between the opposite side and the hypotenuse on a right triangle like this.
There are many different algorithms which can be used to calculate sin(a), but all that I know require a decent understanding of Calculus (Taylor Series) or Trigonometry (CORDIC). You can find a Python implementation of the CORDIC algorithm here.
In a more general sense, the "operation" of the sin function is the "sin" operation. In maths, one very rarely goes lower than f(a) = sin(a) and when one does, it's often just to find an alternate way to estimate the value of sin. One can think of the sin function as being similar to ln(x) in that it is much closer to an operation than being an actual function.

Pop os is my goto recommendation to anybody who is relatively new to linux as it handles a lot of things for you, and there’s guis to configure many of the things that one may want to configure, especially if you’re not quite ready to “live by the commandline”.
I don’t know of a single person who does this. I personally only wear shoes in my house if I am leaving but forgot to get something and need to quickly grab it.
