Listen I know we need a lot of variables in math. A single alphabet won’t due. So capital and lower case letters can be different variables. I can even roll with the idea that letters of the same case in different *typefaces* can be distinct— but, I still find the abusive use of C in Hoggs Mathematical Statistics a little extreme… we couldn’t get more distinct typefaces? How many students have cried because you did this, Hogg? (i otherwise love this textbook it’s so much fun) /math rant
@futurebird I favor using acronyms for increasingly complicated (and obscure) functions. Somewhat obscure to me, and more so to the general math audience. After all, gcf and lcm are awesome successful acronym-named functions. I have a couple functions I’ve worked out acronym names for that I use a lot, but I would have to look up the names I invented for them.
