convergent or divergent??
i took a calc 2 quiz today and had a question on one of the. it's too late to correct what i did, but it's never too late to learn it for the final haha
here is the problem
they want us to find the sum of the series (below) from 1 to infinity (i don't know how to code it so will try my best to represent it)
inf
E (-1)^n * n/(3n +1)
1
i need to find if it is conv or div.
i jumped straight to test of divergence which states that if the limit of the the function as it approaces infinity of (An) "function" does not approach 0 then it div. i know limit of the
n/3n+1 is 1/3 so i said that the function diverges but did not know what the (-1)^n did. would that change it any? or was i right?
