1. The problem statement, all variables and given/known data evaluate the limit. lim x -> infinity sin2^x / x^4 2. Relevant equations squeeze theorem. 3. The attempt at a solution I believe the squeeze theorem could be relevant here. also, i know that sin 1 is 0. so couldn't this problem be something like 0 < sinx/ x < 0 thus also making the answer 0? am i on the right track, please help, thanks.
