More often I need some techniques to use in my area or field of research and generaly I do not have the sufficient knowledge to use these techniques.
Let say for example that I need to prove some lemma in my research paper and I have to use probability theory for the proof. If I ask the question in Math stackexchange forum, people will ask me what did you try? In the other hand, I do not have the sufficient knowledge and I cannot go and start reading the probability theory to do my proof.
How can I ask my question properly so I can respect the terms of use of the website and how can I cite the proof if I get it from someone?
