I have the Maclaurin series for cos (x), is their a way to find its radius of convergence from that?
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)

You should have found that for *any* value of x, the limit the ratio test gives is always less than 1, hence the series converges for all values of x and we say the radius of convergence is infinity.
