1. The problem statement, all variables and given/known data an = [sin(n)]/n Prove that this sequence converges using Cauchy theorem 2. Relevant equations Cauchy theorem states that: A sequence is called a Cauchy theorem if for all ε > 0, there exists N , for all n > N s.t. |xn+1 - xn| < ε I do not know how to approach this proof. I would appreciate some help.
