1. The problem statement, all variables and given/known data Prove that the following sequence (a(n)) has the property that a(n) tends to infinity as n tends to infinity. 2. Relevant equations a(n)=[n+7]/[2+sin(n)] 3. The attempt at a solution i tried l'hopitals rule, so i got 1/cos(n).....which wouldnt work. so im not sure how to do this question.
