As far as the triangular grid goes, it's not common, but is very useful when you need it.
Ternary diagrams are probably the main use for it. They're particularly common in the geosciences as many classification schemes and solid-solution phase diagrams are defined in terms of a mixture of three components.
I used it through most of undergrad to make ternary diagrams by hand (and had to remember and draw in various classification schemes off the top of my head).
It's hard to find, so I would guess that professors are still handing out badly photocopied versions of an ancient sheet of triangular graph paper. (Sure it would be easy to create a nice blank ternplot with grids in $plotting_package_of_choice, but what's the fun in that??)
- dragonwriter 11y agoIts very much not hard to find triangular graph paper today. It may be hard to walk into a brick-and-mortar retail store and find it (though I wouldn't be surprised if campus bookstores in places where it was used in courses carried it), but its quite easy to find online, both printable and pre-printed. So there's really no real reason anyone should be relying on "badly photocopied versions of an ancient sheet of triangular graph paper" (that's not saying that there aren't people doing it, just that there's no good reason for them to be doing it.)
- jofer 11y agoGood point. I'm sure I could order it from Amazon/whatever and have it here day-after-tomorrow. My memory of "very hard to find" meant that 15 years ago the campus bookstore didn't carry it. I'd still bet that badly-photocopied sheets of ternpaper are being handed out on a daily basis in Petrology classrooms around the globe, though :)

I used it to get a hex grid when explaining Pascal's triangle to my kid.
