Coefficients on the p-adic expansions

  1. Feb 27, 2015 #1
    So a p-adic expansion of a rational number was presented to me as an analogue of a Laurent-series expansion and defined as:
    Can you find the coefficients for these the same way you would for a Laurent series? I've not gotten to that part of this book, but it mentions calculus on the p-adics.

    I've also resolved this question. Derivatives aren't defined on the p-adic numbers. And there is no "formula" for finding the coefficients.
