Welcome! This is a community for those that need help with math questions. The idea is for respondents to teach how to solve the problem, not to simply provide an answer. The Original Poster (OP) should aim to attain a real understanding that will lead to independent success in math going forward. Respondents should provide guidance and support to help OP complete the work and learning they need to grow in mathematics.
To get effective help:
Include the complete, exact statement of the problem. Paraphrasing or excerpting the problem can leave out important details.
Include a description of what you have tried, where you feel you are stuck, and ask specific questions about any part of the question you don’t quite understand.
If the problem is part of coursework, specify what course you are taking. If the problem is something you are tackling as part of independent study, provide a basic description of your level of education in math. This will help respondents provide answers that match your level of understanding.
To provide effective help:
Do not provide the answer outright. This doesn’t help the OP grow and learn for themselves.
Do not provide complete, step-by-step solutions. Again, this doesn’t help the OP learn to tackle future problems for themselves.
Do provide a hint about what sorts of questions OP should ask themselves, or suggest special cases or ideas they should consider as they work through the problem. This points out the important features or the problem, but lets OP make the connections for themselves. Learning happens when a student discovers the connections between ideas.
Do look for misunderstandings the OP might labor under, and clarify how those misunderstandings are blocking a solution.
Pitch your answers to meet OP’s stated mathematical level.
