Here is my suggestion: Randomly select 20 calculus textbooks in a
library. A word or phrase is "a well established mathematicalshould
term" if it is found in at least 80% of textbooks. The textbooks
be up to 60 years old. Why up to 60? Because I was introduced toThese
these
two terms about 60 years ago. They were in Polish -- zmeinna zalezhna
and zmienna niezalezhna.
Why not just take a poll of Phys-l members? Although we are not
professional mathematicians, most of us are familiar with "well
established mathematical terms". I, for one, think that "independent
and dependent variables" are well established mathematical terms.
terms appeared in many texts I learned mathematics from in highschool,
college, and graduate school (although graduate school was 40 years
ago).
Has usage changed in recent times?
