It wouldn't surprise me if Spanish had different conjugations for the word
sine depending on whether :-
I do the sine function
You (familiar) do the sine function
You (formal) do the sine function
He does the sine function
She does the sine function
We all do the sine function
You all (familiar) do the sine function
You all (formal) do the sine function
They (them over there) do the sine function
... and then a whole lot of additional permutations depending on whether performing the sine function was done in the past, present or future!
