so how would you use this notation for hyperbolic or elliptic trig functions?

it's confusing to learn 6 new similar symbols instead than 6 new words.

The proper shorthand is C,S, and T, as well as C^{-1}, S^{-1}, and T^{-1} for the inverses.

Yes, now make them into unicode, so I have to use more movement to place it in calculator. Aren't you guys retarded or something?

C S T are cos, sin, tan
Cotang is just T^-1, sec is C^-1 etc
Inverses: AC AS AT
A can be thought as an inversion operator, then:
ARCCTG is then A o T^-1 etc.

This is too much voodoo. Three letters are infinitely clearer and maybe faster to write.

Ah, this was the trig notation proposed by Feynman, no? I like it, has an intuitive touch to it, though I can understand how boring types would hate it.

It really only works for him though. They don't convey anything to me. He stated in one of his public talks that he stopped using these later when he got to uni and research bc people had no fucking idea what he was trying to convey.
