    Hello and welcome to MathHelpForum.
    You should understand that this is not a homework service nor is it a tutorial service.
    PLease either post some of your own work on this problem or explain what you do not understand about the question.

    You missed the point completely.
    We cannot help if we do not know what you do not understand.
    None of us here is a mind reader.

    In that case you did not read my first post carefully.

    We are no prepared to teach you anything about this material.
    You need to hire a tutor.

    The word help implies correction to misunderstandings.
    You want to be taught this material.
    We do not do that.


    Moderator edit: MHF stands for Math Help Forum. MHF helps students with specific questions. MHF does not teach course material, that is the job of the student's instructor or a tutor.

    There is a reasonable assumption that a student understands something about the material the question relates to and can show some work or say specifically where s/he is stuck with the question. If a student understands nothing, then that student requires more than MHF can provide.

    Thread closed.
