    Showing a function to be analytic...

    Let f and g be ananlytic on a domain. Show that:

    f + g is analytic on D and (f + g)' = f' + g'


    I also have to do this for fg and f/g. Can someone show how to do the above, so I can attempt fg and f/g on my one?

    Thanks in advance for any help...

    Well I figured out how to prove (f+g)' = f' + g'

    But what do I need to do to show this is analytic?

  5. Is this correct? - showing analytic function is constant.
