Thanks to several viewers, at Q25,
1:53:40 , n should go from "2" to inf. And in that case, cos(pi*n) will produce 1,-1,1,-1,... but it is still a convergent alternating series.
Thanks to Chester, at
2:34:35, I meant to say 1/3 is less than "1", not 0. So we can draw a conclusion from the Ratio Test.
Thanks to Alberto! At
4:52:58 the final answer should be x is less than “-1”
