Analytic Formula

  1. Apr 24, 2010 #1
    1. The problem statement, all variables and given/known data

    Derive an analytic forumula for a CDF

    2. Relevant equations



    3. The attempt at a solution

    All I really want to know is what an analytic formula is? I know that the CDF is basically an integral of the PDF. I have looked all over the internet and can not find anything of the definition of an analytic formula.

    Thanks!

    Unless they have a specific CDF F(x) in mind, perhaps they just mean

    [tex]F(x) = \int_{-\infty}^x f(t)\, dt \hbox{ so } F'(x) = f(x)[/tex]

    Edit Corrected typo.

    Thanks. That's what I kinda figured, but I wanted to make sure that is what they ment.

    Thanks again!

    Hi can someone help me please? I am trying to do the following problem:
    Prove that if f(z) is analytic, f*(z*) is also analytic. The stars represent conjugates. Thanks!
