Hi, i'm trying to understand how i can write on wolfram alpha a series where i have a variable and i need to study the caracter of the series.
here an example, i have the series of
[n-arctan(n!)]/n^x with n=1 to inf and x>0
how can i write inside wolfram alpha so that it tells me for which values of x the series converge or is divergent
thank you
