The rate of convergence of a sequence

Click For Summary
SUMMARY

The discussion focuses on determining the rate of convergence for the sequences limn→∞sin(1/n) and limn→∞sin(1/n2) as n approaches infinity. Both sequences converge to 0, with the approximation sin(x) ~ x for small x being a key analytical tool. The sequences can be analyzed using the terms 1/n and 1/n2, highlighting the difference in their rates of convergence.

PREREQUISITES
  • Understanding of limits in calculus

It's been a while since I've done rate of convergence problems,
how would i find the rate of convergence for either of these sequences?

1) limn->infsin(1/n)=0

2)limn->infsin(1/n^2)=0

For small x, sin(x) ~ x. Therefore your examples can be analyzed by using 1/n or 1/n2.
