Determine if these diverge or converge. if it converges, what is the limit? Show all work please. I have a test next week...and i have no idea how u do this...I just know you need to use L'Hopital's rule, but theres also manipulation, and i duno how to do it!!!

1)An = sin^2 n/ sqroot n

2) An= ln n / sqroot n

3) An= (2^n)+ 1/ (e^n)

please help!
