Homework Statement
I am doing a proof about limits, and I need to know the range that sin(n^3-2n)/n is within for all n.
Homework Equations
The Attempt at a Solution
I know that sin(n) is in between -1 and 1 for all n, so sin(n)/n would be in between -1/n and 1/n for all n. However, I don't know how to manipulate the range if the inside of the sin(n) function is changed. Any help would be great!
