Thanks. Last question. So then, if the limit c of the ratio test isn't between 0 and 1, I can't say for sure if it converges or diverges, but if it is between 0 and 1 it converges for sure? did I got that right?
I tried a comparison test and yes, I can solve it with that. But the problem is inside the ratio test problem set, so it should be solvable with a ratio test, or at least mixing ratio and comparison, going by how the book is structured (book is "A First Course in Calculus" by Serge Lang). This...
Hi. I have been banging my head against this problem for a while and I just don't get it. Maybe (probably) it's something wrong with my logarithm-fu or limit-fu. I just registered to ask this because I couldn't find an answer anywhere, and I've been reading these forums for a while for other...
