Given the limit
lim(x→0) x^4 cos(5/x)
use the squeeze theorem to find g(x) and h(x) given,
The Attempt at a Solution
well the limit with x=0 substituted in would mean the limit is undefined as,
(5/0) can not occur but due to the function being trigonometric the usual use of 0^- and 0^+ can not be used, i found as -1≤cos θ≤1
i have no idea how to find the g(x) and h(x) with only an f(x) function, can anyone please talk me through how to use the squeeze theorem for this problem???
