Halves?

KooyeenHi,
sorry if this is not the best section to post about this, but I really didn't know where to post. And since it's an unusual question, I figured here it would be noticed by most people.
How should I read this?

x/2
cos(pi/2)
tan(B/2)

Ex halves? I don't think it's half x, or x half.
Cosine (of) pie h

Hi Kooyeen,

#1 Ex over two

#2 Cosine of parentheses pie over two

#3 Tangent of parentheses beta over two

Somebody else might tell you otherwise. You hafff to be very specific about the ( )'s . If you said, "Cosine [of] pie over two" it could be (cos pi) / 2

Hi Avangi,

I like

Hi,
I don't have to be specific. Actually, I don't want to, lol. I just have to read them the way people (lecturers or students) read them most of the time.
I searched Youtube... Everyone says "pie over two", but someone said "pie

If I heard "pi thirds" I would NOT think it was pi over 3. I'm not sure what I would think, but it sounds ... uninformed.

If you're being very precise, instead of "parentheses" I've also heard "the quantity of."

Cosine of the quantity of one-haf pi or Cosine of the quantity of pi over two

I've heard "one-half pie," but "pie halves is a new one on me.

This could muddy the waters.

X = Cosine (pi / 326) - how do we say that?

1. "X is equal to cosine of the ratio of pi over three twenty six."
2. "Let A equal to pi over three twenty six. X is equal to cosine of A."

Hi Hoa,

I really don't subscribe to these convoluted constructions. Are we addressing a group of mathmaticians or a group of grammarians? Go to the source!

Ex equals Cosine parentheses pie over three-twenty-six - no confusing ambiguities.

Edit. I think there must be some foundation for GG's approach to parentheses: use "quantity" to represent the results of whatev

I see, but I don't want ot be precise... I only have to read that, not tell someone on the phone.

Hmm, what's wrong with that? And what would you understand?
I just asked a native speaker who knows math, and he says "pi halve

I have never heard that.

I went to univeristy to study engineering. I took more calculus classes than I care to think about. I have NEVER heard "pi over 3" or "one-half pi" expressed as "pi thirds" or "pi halves." Honestly, if someone said "pi thirds" I'd have to ask them to explain.
