Ray, isn't the limit of k the summation? So, it would be infinity? I just finished reading sequences and series but prof. is already 3 sections ahead. Stewart's Calculus isn't helping so these instructional google videos (e.g. Khan Academy and prof. Leonard) slow me down. Halls of ivy, how did...
I tried the comparison test for one B but not sure if I am right. Think it could also be a ratio test because of the variable exponent. I'm lost totally lost on number one A. Also, I have the answer for the first part of three but don't know how to do the second part of it by comparing.
Thanks
