limit x->+inf sin(sin(x))/x
Let's evaluate the limit of sin(sin(x))x when x → +∞
The limit of sin(x) does not exist but is bounded in [-1, 1] when x → +∞
The limit of sin(sin(x)) does not exist but is bounded in [-1, 1] when x → +∞
ⓘ A bounded quantity divided by a quantity that grows without bound tends to 0
So the limit of sin(sin(x))x is 0 when x → +∞
