# Functions as Power Series

## Homework Statement

I'm having a little trouble concerning the part where we have to calculate the endpoints of a known interval of convergence in order to see whether they are convergent or divergent. In this case, is the summation of n=0 to infinity of (-1)^n/10 diverging or converging. Are there any tests to prove that? I'm kinda confused. Thanks

Have you looked at the alternating series test?

uhh yea, but it just gives bn= 1/10 which doesn;t make sense...i think
