@Gigili Sure, that could be a way even if there are a few ways to 'measure' cooperation.

Actually, I want to know which way of assigning authorship is favored by the community.

What is your personal take on this issue?

@GlenWheeler hi, may I bother you with a quick question about integrals if you don't mind and have the time?

@Trufa: You could probably just go ahead and post a question and someone will eventually get to it.

@ElendiaStarman indeed I should

The above is the function for calculating integrals by aproximation

You divide a range from a to b in equal parts names epsilon

I understand the basics of it but can't figure out why I have to divide the first and las by 2

@Trufa: If instead of f(a)/2 and f(b)/2 you just had f(b), then you would be adding the areas of n rectangles, each of which has height determined by the function value on the right. If instead of f(a)/2 and f(b)/2 you just had f(a), then you would be adding the areas of n rectangles, each of which has height determined by the function value on the left.

@Trufa: Having f(a)/2 and f(b)/2 there means that you are averaging the left- and right-hand approximations. This is known as the trapezoidal rule: en.wikipedia.org/wiki/Trapezoidal_rule

@JonasMeyer hmm ok, lets see... I'm cheking out the wiki, thanks!!

@JonasMeyer I think I undertood what you mean

@JonasMeyer ok ok I got it now

thanks for the link

the python script helped me out a lot

@Trufa: Good to hear!

@JonasMeyer ok, that was helpful! Thanks again, you saved my butt :)

A question, How you answer a math question without having integral and sum and other thingy ..

@Trufa Hi Trufa, sorry I wasn't around at the time you asked. In the future, every question should just be posted on the main site. If it's not appropriate, it will be dealt with, don't worry :).

@GlenWheeler Thanks for the advice and, of course, don't worry about it!

Maybe the rules are a little bit different here, but I participate mainly in Stackoverflow, and I try to get rid of the quick and dirty questions on the chat.

But if I have "real" question, I will sure post them!

Thanks again!!

@RobertSmith I don't understand where the problem lies, but If there's no way to measure cooperation , how you know levels of cooperation are not equal?

@Gigili I do think there are ways to measure cooperation although I don't think they are extremely obvious to get everyone satisfied with the overall result of that. As for your question, I'm interested in a situation in which there is an online collaboration to solve a technical problem. Most of the time, in that kind of collaboration, the levels of cooperation are unequal (you know, there a few who are engaged in the task fully, others who are more casual in their participation, etc).

@Robert Smith - Have you heard of the Hardy-Littlewood Axioms of Collaboration? :]

The fourth stated that it was quite indifferent if one of them had not contributed the least bit to the contents of a paper under their common name . . .

I first came across this on MO thread on the same subject. Might worth a search.

@RobertSmith you've probably noticed that I made your question the main discussion. no costs, be our guest. =)

@Prometheus Great article or whatever.

@Prometheus Very amusing! (by the way, I didn't know about it, although it seems like a recipe for disaster except when you're collaborating with Hardy, Littlewood or for that matter, the mythical creature called Hardy-Littlewood )

@Gigili I noticed that! Thanks for that (particularly because it was at no cost :-))

Just a quick question that doesn't really belong on the main site, but what does the notation Z/pZ mean?
