Would the following series be conditionally convergent, absolutely convergent or divergent?
∞∑k=1ksin(1+k3)k+lnk
Whereas for sine functions in series like this, you can usually say that it just alternates between 1 and -1 but would this one do the same for k≥1? I don't think it would so that would mean I can't use the alternating series test. Perhaps, then, the ratio test or some comparison test?
