1. The problem statement, all variables and given/known data I'm supposed to evaluate the following series or show if it diverges: SUM (sigma) log [(x+1)/x] 2. Relevant equations Drawing a blank... 3. The attempt at a solution I'm unsure how to start this. We've gone over all sorts of tests for convergence (ratio, comparison, p-series, etc), but I'm not sure what to do with the log function. A push in the right direction would be appreciated! Thanks.
