Hey there.
This thread is to provide a brief guideline for those asking for help with science homework, etcetera, and to those who wish to provide help.
There is absolutely no problem with asking for help with science or maths work in this forum if you are stuck, especially if your question is an interesting one which will promote discussion; given the large number of welleducated members at DV, you can be fairly sure of receiving an answer.
However, this forum is not here to provide a service to those who just want an answer to write down for tomorrow's work because they do not want to put in the effort to think about it themselves. Answering these questions would be a waste of DV members' time, and, more importantly, by providing a crutch without actually educating the asker about the basis of the question, would be detrimental to their study.
Therefore the following is advised:
Guidelines for Questioners
If possible, do not relate the full details of the question. If you know which specific area the question is getting at, ask for some general help about that area. If you are getting stuck on a part of a question, just ask for help with that particular bit.
If you do feel the need to post the entire question however, please refrain from posting the actual numbers (if there are any) in the hope of getting a numerical answer from another member which you can just write down.

Guidelines for Answerers
Do not do the entire question. If the asker did not specify, ask them what in particular is confusing them. Try to apply the Socratic method and explain the basis of the question, rather than telling the asker how to solve their specific problem.
In particular, if the asker gives numbers, do not provide a numerical answer. If they provide symbols, indicate which formulae they may need to apply, but do not solve the formulae so as to give the final answer in symbolic form.

The thing to bear in mind for all is that we want education and discussion rather than answers.
Thanks.
