Derivative of complex number

  1. Nov 7, 2007 #1
    If I have a function y = if(x), where f(x) is a real valued function, would its derivative be y'=if'(x)...or does something different have to happen with the i part?

    i is a constant, isn't it?

    that's what I thought, but I like to double check these things... =)
