In the thread Random Chatter, there are 36 full pages of posts plus 1 post on the 37th page and since I have my preferences set to displaying 75 posts per page, there should be 2701 posts. It says 2700.

Similarly, at the time of writing this, I have 3202 posts. In my profile viewing my posts, there are 42 full pages of posts plus 9 posts on the 43rd page which would account to (due to me having my preferences set to displaying 75 posts per page) 3159, not 3202.

Nice jokes, ganesh!

Here is another one

A person named ganesh told someone a math joke.

Q. Why was 6 afraid of 7?
A. Because 7 8 9!

The person who heard the joke said:

If you take the courses in US online or at summer or night school, you will be able to graduate early. Of course, are you willing to move countries just to graduate one year early?

AP doesn't really matter if you are going to take many courses online and it isn't much of a difference compared to regular classes anyway.

Here, we have two different names. The numerical coefficient of 34 in 34abc is abc and the literal coefficient of 34 in 34abc is abc.

I got, I think, a 70% in English as well - it doesn't matter much, to be honest.

And I don't think a student will get a mark off on a test for saying 2 is a coefficient or isn't.

What does everyone think about that?

To be honest, it isn't too big of an issue. Such terminology discrepancies occur all the time and it is just a matter of convention (e.g. in the UK they use R^d instead of R^n like here in the US in real analysis).

This is what I mean

in 2x + 1, 2 is a coefficient of x

However, 1 is not a coefficient - it is a constant.

In 2x + 1x^2 though, both 2 and 1 are coefficients.

#221 Re: Maths Is Fun - Suggestions and Comments » Coefficient vs Constant » 2014-06-13 11:30:52

Me too. But I wouldn't say 1 on it's on is a coefficient.

According to Wikipedia

Wikipedia wrote:

For instance in 7x^2-3xy+1.5+y the first two terms respectively have the coefficients 7 and −3. The third term 1.5 is a constant.

#222 Re: Maths Is Fun - Suggestions and Comments » Coefficient vs Constant » 2014-06-13 11:27:40

I would say that 2 is a coefficient of x in that expression.

#223 Re: Maths Is Fun - Suggestions and Comments » Coefficient vs Constant » 2014-06-13 11:25:53

How about this:

2

Is that a coefficient? I think most people would say 2 on it's own is not one (that's just my thinking).

#224 Re: Maths Is Fun - Suggestions and Comments » Coefficient vs Constant » 2014-06-13 11:22:41

I think the way it should be is if we have a number a, we can't say it is a coefficient. 2 is not a coefficient. However, I think we can say that 2 is a coefficient of 2x^0.
