I have the Maclaurin series for cos (x), is their a way to find its radius of convergence from that?(adsbygoogle = window.adsbygoogle || []).push({});

ALSO

Is there a trick to find the shorter version of the power series for the Maclaurin series, I can never seem to find it so instead of the long series with each term but like E summation (the series)
