Why sin and cos don't mean anything

Get better at maths with Brilliant: https://brilliant.org/SimonClark/ An excellent summary of this story (found after I did all the research, annoyingly!) can be found here: https://physics.info/trigonometry/ So, yes, the title is, rather than trigonometric, slightly hyperbolic. Sin and cos are a corruption of the word sinus, and so do have a lexical root and broader meaning. But the point I'm trying to make here is that there is no connection between the word sinus and what the functions actually correspond to. Any true meaning was lost in the successive translations and transliterations from sanskrit. So while sin and cos do have /a/ meaning, I guess what I'm saying is that they don't have a /meaningful/ meaning. Also I apologise for any pronunciation mistakes in this. I'm a scientist, not a linguist! Also also yes I'm aware that there are differences between Persian (in various stages) and Arabic.
