I was just wondering...
Do russians, when studying maths or any other exact science, use the variants(x, y, etc) in cyrillic or latin alphabet?
I mean... for example, how do you READ this in russian?

We don't use cyrillic letters in math, physics, chemistry or other exact sciences. Traditionally only latin and greek alphabets are used.
x
y = игрек?
How sweet!
Then the fatorial is read like what? "эн факториал" or something?
Yep. :)Quote:

I don't remember for sure since I haven't read a math book for ages. It's either "эн факториал" or "факториал эн/факториал числа эн". But don't worry too much. "Факториал" is a key word and you'd be understood in any case.Quote:

There is a joke of a lazy student who skipped math lecture on factorial. So then when he copied abstact of this lecture he thought that factorial stands for an explamation mark. On the math exam professor asked him of factorial and when answering professor's question student emphasized each Latin letter that is followed by a factorial.

Latin alphabet is used, not an English one. And letter names are Latin also.Quote:

До кучи:
Sum = Сумма
Item = Слагаемое
Difference = Разность
Product = Произведение
Quotient = Частное
Dividend = Делимое
Divisor = Делитель
Multiplier = Множитель
to add = складывать
to subtract = вычитать
to divide = делить
to multiply = умножать
2^2 = Два в квадрате
2^3 = Два в кубе
2^4 = Два в четвёртой (степени)
6! = Шесть факториал
radical = радикал
sqr(2) = \| 2 = (квадратный) корень из двух
3---
\|2 = кубический корень из двух
далее корень четвёртой (пятой...) степени
lg(x) = десятичный логарифм
ln(x) = натуральный логарифм
exponent = экспонента
sine = синус
cosine = косинус
tangent = тангенс
cotangent = котангенс
Неоднократно слышал вариант "жи".Quote:

Yes, I encountered "жи" much more often.Quote:

k-тый (катый)
Aren't these more French namesQuote:

I think you use the French names and not the latin names.
E.g. in Latin the letter H is called Haca, or hic or something.
Yes, it's probably a mixture of French and Latin ("c" is "це" and not "се" like in French) Another difference from French is that it's Игрек in Russian while in French the stress is (naturally) on the last syllable. Here is the Latin alphabet with Russian pronunciation of the letters: http://www.asu.ru/departments/philology ... 01-1.shtml
Most of the French words have the stress on the last syllable. You're right about "c", it's not French but German. This is how they pronounce it when they say the alphabet or spell a word.Quote:

In Russian, it's дэ два эф по дэ икс дважды, IMSMW.
dee two eff
dee eks two
d two f by d x squared
d squared f by d x squared
I've never heard the equivalent of "by d x two".
Silly me.Quote:
