I apologise for choosing not so related topic, but I could'n find better one. I will have to read some math expressions in English for audience and I'm not sure how to say it. And when I ask English teacher, they don't know what it means in the first place and can't give me any advise either. Could you please help me?

Example: a2 = a squared
a×b = a cross b
a+b = a plus b etc.

These I don't know for sure how to say:
an
|r1-r2|
abf(x)dx
d2y/dx2 (second derivative?)
∂y/∂x
a/b

1. a to the (power of) n OR a to the nth
2. Absolute value of the difference of r one and r two
3. Integral from a to b of f of x dx
4. Second derivative of y with respect to x
5. Partial derivative of y with respect to x
6. a over b

Looks like the OP intended vectors here, so I would say "modulus of r one minus r two".

(a over b)

I understand the importance of accurately communicating technical information to an audience. In this case, I would suggest seeking out a mathematics or science teacher who is familiar with these expressions and can provide accurate translations. It is important to use precise and clear language when discussing mathematical concepts, so it may be worth investing some time in finding a knowledgeable resource. Additionally, there are many online resources and dictionaries specifically for scientific and mathematical terminology that may be helpful in finding the correct translations.
