Wheres the problem. At least ive written the whole question again in MS Word then used the print screen feature. I can see that your are doing so much work in commenting rather than helping. If your willing to help then thanx if not then no need to even view my topic.

So is that the way that you give a good impression to a newbie on mathforum.org. Showing off and commenting. Well see man if your willing to help then thanks. If not no need to post in the first place. Someone else will take over :-)

I never use mathforum.org . Whatever facility you are using on mathforum.org
is a pretty wrapper around the Usenet newsgroup comp.soft-sys.matlab .
There is another pretty wrapper for the same newsgroup, at http://mathworks.com/matlabcentral . Google Groups has a third pretty
wrapper for the same newsgroup. But it -is- a Usenet newsgroup,
and Usenet newsgroup rules and etiquette apply.
>Showing off and commenting.
Showing off? No, merely posting verifiable facts demonstrating that
you were in error when you claimed that I spent a lot of time commenting
and not much time helping. That you were quite wrong on that point
should hint to you that you might perhaps be wrong on other points.
>Someone
>else will take over :-)
Oh, indeed, indeed.
Did you perchance read the following thread from two days ago?
Dude, you seem to have the wrong idea about this newsgroup.
It's for asking questions ABOUT MATLAB not asking questions
that can be answered in matlab. You should post the code
you've tried and ask questions about why it isn't working,
and you'll get a much warmer reception. When you don't post
any code, it seems like you just want people to do your
homework for you with no effort on your part. Most of us
here (having been through college ourselves) consider that
unethical and don't want anything to do with you.
Disrespecting our most helpful posters is also going to get
you nowhere.
Subject: Re: Matlab Help needed that will allow you to compute the flow..
Thats what i call a respectful mature post. Problem was that i did not put effort ? yes i did. But i wasnt sure if i had to show my work. Thanks for guiding me over. The second post should have said this. We shouldn't have gone over all that arguing part. Anyways , back to subject:
Im not really sure whats asked in this problem, i think i'll have to go back to a fluid mechanics book. Any tips would be grateful.

That doesn't count as putting in effort on the homework. Will
your professor give you credit for typing this and doing a
screen capture?

That is because the professionals who are regulars in
technical newsgroups consider "help" on homework to
consist of teaching, rather than just doing the homework
for the students. And so they take the time to instruct you
on the best way to get help, rather than simply doing
the problem for you.
However, if you really want somebody to just do the problem
for you, give me your teacher's e-mail address and I'll send
in a solution.

Alas, this is a common response from students who got
the help they needed (patient instruction), rather than the
"help" they wanted (cheating).

Actually yes im doing print screens and putting them in a DOC file.
BTW i really like the way you reply. This is the way i like to be treated and talked to. With all you repsect randy Im really sorry for what i said earlier to the members that were trying to help :-)
My Fault. There was a misunderstanding :-).
Back to subject :-) Is my solution correct ?
Subject: Re: Matlab Help needed that will allow you to compute the flow..
Instead of posting screen shots, I suggest that you copy the code you've
written into your post. That way, it's easier for anyone who wants to help
to run the code (to see if the code or their modifications to it execute
without throwing an error, for instance.)

The reason for me not to type a thing or an equation here is that if my class mates use google to do a search with differnt keywords everytime they will finally click and the google search pages will lead them up to here. The same solution as mines. We will all end up with a "0" Grade. Thats why im using picture in all threads that i have started. I hope im making sense.

In my opinion, "giving someone the finger" is completely inappropriate
in a professional situation.
Do you recall what you started out by saying? That if people didn't
like your postings, that they should just not reply? If you
believe that principle, then is it not the case that you should
simply not have replied to the posting that prompted your graphic?
I would put to you the suggestion that you thought you were being
treated disrespectfully, and that you responded by expressing
discontent at that perceived disrespect. I would then put to you the
suggestion that earlier on, some of the posters believed you were
treating people (or the newsgroup collectively) disrespectfully, and
that they responded by expressing discontent at that perceived
disrespect. Few people enjoy being disrespected; the difference is in
the manner of expressing that discontent.

That does make a bit of sense, in a way, but it does not happen to
take into account the nature of newsgroups such as this one.
Conversations in newsgroups such as this one are public, deliberately so.
We do not provide assistance just to the one person who happens to ask
the question: we write "for the record", knowing that the messages
will be archived and available for the edification of anyone else who
seeks out and reads the messages.
Our purposes here are not targeted at helping out individual students
with their assignments: our primary purpose is to help as many people
as practical learn -- and that word really is *learn*. Sometimes
teaching consists of giving answers directly, and sometimes teaching
consists of refraining from giving answers directly, instead
guiding the questioner on how to uncover the answers for themselves.
For many of us, our purposes here are guided by the spirit of
scientific cooperation, the -sharing- of information and skills for
the advancement of knowledge; our answers are "open answers" for the
benefit of as many as can find them useful, and deliberately
restricting our answers to be of benefit to one person only would be
in stark opposition to the reasons why we volunteer our time, knowledge,
and intelligence.
When it comes to particular assignments: to the extent that we teach
how to -do- the work and do not actually do the work itself, there is
no conflict: if your classmates learn -how- to do the work by reading
the exchanges here but still have to do the work itself, then the
resulting programs will be different. Do not be too concerned that the
general methods will look too much the same in such cases: there are
only a relatively small number of efficient general methods to solve
the kinds of problems you have been posting, so the course markers will
be expecting to see the same broad outlines but different details.
In light of this, the effect of posting images of the questions rather
than the questions themselves, will only have the effect of obscuring
to your classmates that a discussion is taking place here. It is
anti-thetical to our purposes to obscure the dissemination of knowledge.
If one of your classmates finds their way here and learns from what
has been previously discussed, then as far most of us
are concerned, that will have been a *success* for the newsgroup's
teaching purposes. Do not expect us to take any particular care to
avoid using any particular words that might attract the notice
of your classmates.
You should thus consider that the primary risk to you is if you post
your code and that others might copy it. There are techniques to reduce
that risk. One of the most valuable of those techniques is not to post
assignments at all, and instead to ask us questions about the *MATLAB*
part of your work.
Questions such as "how would I sum a number of computed terms?" can be
answered with basic Matlab code applicable to any of a number of
programs. This newsgroup is, after all, not intended as a newsgroup in
which to study thermodynamics or fluid mechanics or the like: our
assumption is that if you do not understand the field of study you are
undertaking, that you will seek out sources and forums appropriate to
that field of study, and that you will post here when it comes to
matters of applying MATLAB to the methods you have already worked out.
If you encounter an error message you do not understand, it -usually-
suffices to post the complete text of the error message and a few lines
of context. If we are unable to figure it out from the sample,
then if you have posted enough to demonstrate that you are learning
and are not "asking for a hand-out", then it is considered acceptable
to post saying something like, "Sorry, this is part of a class assignment
that I am working on, and I cannot post the code because of concerns
over classmates potentially copying it; is there anyone who would
be willing to look at the code privately, via email, and see if they
can spot the error?"

In my experience, what turned out to "help me with my career"
was often not the subject matter itself, but rather
"the way of looking at things" that the study of the subject
introduced.
Numerical analysis wasn't my favorite subject at University, and I
doubt I could remember now even a single course assignment. But a
number of times, knowing that numerical analysis existed and was
important for some kinds of problems, and knowing the very basics of
how to do it, has turned out to be important for producing
robust solutions to my work of the time. I don't use it every
year, sometimes not even twice in five years, but when I do
need it, I can go back to the fundamental way of thinking about
formula that the course taught, and mentally rebuild what I need
from that.
You haven't happened to mention what your "career" is. If you had asked
me in University what my "career" was going to be, I doubt whatever I
would have answered would have matched very closely to what I have
ended up doing. For many years, the best description of my job would
have been "Whatever needs to be done!". Corporate headquarters wants an
answer as to whether we want to split the cost on a new piece of
equipment? -Someone- has to learn about what the equipment does and
does not do, and assess how our needs match the equipment's
capabilities (and shortcomings), do a full pricing, assess other (much
less expensive) models for cost effectiveness, and get clarification
from HQ about what their intensions are. Did we have a month? No, we
had two business days. "Careers" are not made up of noble intentions to
be "An Electrical Engineer" (or whatever); careers are made up of
endless series of specific work tasks, and if you are working in a
challenging "career", then urgent crises will probably come your way
routinely. This elective course you are taking, if nothing else, gives
you an opportunity to learn how to work under pressure. Better that you
should have that opportunity to learn now, while still in school, then
to bit hit with it on the job and to "freeze up", overwhelmed.
