You seem to be using a number of "special symbols". All my viewer shows is a square for each.

ok...i will reformulate the question
find the limit as n tends to infinity, if it exists of
1. root(n(n+1))-2n

2. n*sin(1/n^2)
Thanks...:)

For the first one, multiply out what you have in the square root and pull out n2 from the square root.
For the second, you might try the substitution u = 1/n
