already has an established notation:
Accidentally sent that prematurely.
I meant to say that changing the notation will only lead to confusion.
Also there are good reasons for using short names in equations. It makes it
much easier to see the whole equation at once, which makes it easier to
understand the equations and easier to check your code. If you make the
variable names too long, even simple equations like these will have to
split over several lines and be more difficult to read/check.
