Homework Statement
f(x) = x^3 [cos(pi/x^2) + sin(pi/x^2)] for x≠0
Homework Equations
The Attempt at a Solution
I really am stuck.
I've tried squeeze theorem on [cos(pi/x^2) + sin(pi/x^2)], but I can't compute the range.
So, I tried doing it individually, squeezing -1 ≤ cos(pi/x^2) ≤ 1, but that doesn't work.
Any hints please?
