I was tasked with determining whether the following series:
∞∑n=1tan(1n)
converges.
I tried employing the integral test which failed and produced incalculable integrals. Other methods didn't prove effective also. I was suggested that the Maclauren series might be of use here, but I'm not sure how to employ it.
Answer
Or by limit comparison test with ∑1n since by standard limit for x→0⟹tanxx→1 and then
tan(1n)1n→1
