The limit of x^2 sin(1/x) as x approaches 0 is equal to 0, and it is denoted by limx→0 x2 sin(1/x) = 0. So the limit formula of x2 sin(1/x) when x tends to zero is given by
limx→0 x2 sin(1/x) = 0.
We will now find the limit of x2 sin(1/x) using the Sandwich/Squeeze theorem of limits.
Limx→0 x2 sin(1/x) using Squeeze Theorem
We know that sinθ lies between -1 and 1 for any real values of θ. That is,
-1 ≤ sinθ ≤ 1.
So we obtain that
-1 ≤ sin(1/x) ≤ 1.
As x2 ≥ 0, it follows that
-x2 ≤ x2 sin(1/x) ≤ x2.
Now taking the limit limx→0 on both sides, we obtain that
limx→0 (-x2) ≤ limx→0 x2 sin(1/x) ≤ limx→0 x2.
⇒ 0 ≤ limx→0 x2 sin(1/x) ≤ 0.
So by the Squeeze theorem, we get that limx→0 x2 sin(1/x) = 0.
Thus, the limit of x2 sin(1/x) is equal to 0 when x tends to 0, and this is proved using the Squeeze theorem. That is,
limx→0 x2 sin(1/x) = 0 |
