Question: is there a misprint?

  1. Feb 1, 2009 #1
    This isn't a homework question; I'm sorry if I'm mis-posting, but I thought someone here could help.

    See this link:

    On page 56, does this book have a misprint in the definition of a differentiable complex function? On 5.1? Shouldn't the bottom of the quotient be 'h' instead of 'z'? I'm probably misreading or something. But I'm confused at why h is at the bottom of the quotient further down the page.

    I don't know, maybe I'm being silly and there's something right there that I'm missing? Please help me out, thanks!

    Yes this is a misprint.

    It looks corrected when they use it towards the bottom of the page.
