Derive an analytic forumula for a CDF

Homework Equations

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

$$F(x) = \int_{-\infty}^x f(t)\, dt \hbox{ so } F'(x) = f(x)$$

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!
