Hey, I need help with the following problem: Determine whether the sequence converges or diverges. If it converges, find the limit. an=tan[(2npi)/(1+8n)] Thanks!

Note $\displaystyle (2\pi n)/(8n+1)\to \pi/4$. Since $\displaystyle \tan$ is continous, by definition, $\displaystyle \tan (2\pi n/(8n+1))\to \tan \pi/4= 1$.
