I have a function $g(x)=x^4 \cos(2/x)$.
I have to use Squeeze Theorem to show $\lim\limits_{x\to0}g(x)=0$.
Usually all the questions I have done up till now on Squeeze theorem have provided me with 3 functions, 1 function is less than another. 1 function is the highest of them all. and 1 functino is in between the 2 functions. From there I have been able to prove the limit with squeeze theorem but in here I have no other function so what do I do here?
