Homework Statement
ok, this is the limit i want to calculate: limit x->0 sin(1/x) / (1/x) and
limit x->infinity sin(1/x) / (1/x)
can you tell me the clear step mathematical proof
2. The attempt at a solution
now the first one i tired doing this, let u =(1/x) then: limit U->infinity sin(U) / (U)
now i understand its actually zero since, sin(U) goes back between -1 and 1, when u grows to infinity so its zero...so what's the mathematical proof.
