i have a question regarding adsolute and conditional convergence of alternating series.(adsbygoogle = window.adsbygoogle || []).push({});

- i know that summation of [ tan(pi/n) ] diverge, but how do we proof it converge conditionally? (ie, (-1)^n tan(pi/n) ]

can Leibiniz's theorem be used in this case? but tan(pi/2) is infinite?

any help is appreciated. =D
