I have learned that if a function of one real variable can be defined as a power series, then this one is its Taylor series.(adsbygoogle = window.adsbygoogle || []).push({});

Does the same occur with functions of 2 real variables? I mean, if a function f(x, y) can be defined as a power series, does this series is the Taylor series of f(x, y)?

Thanks for help.
