The limit of sin(√x)/x as x approaches 0 DOES NOT exist, that is, the limx→0 sin(\sqrt{x})/x formula is given by
$\lim\limits_{x \to 0} \dfrac{\sin \sqrt{x}}{x}=$ not exist.
Let us learn how to find the limit of sin root x divided by x when x tends to 0.
Find Limit of sin(√x)/x when x→0
We have
$\lim\limits_{x \to 0} \dfrac{\sin \sqrt{x}}{x}$
= $\lim\limits_{x \to 0} \dfrac{\sin \sqrt{x}}{\sqrt{x}} \times \dfrac{1}{\sqrt{x}}$
= $\lim\limits_{x \to 0} \dfrac{\sin \sqrt{x}}{\sqrt{x}} \times \lim\limits_{x \to 0} \dfrac{1}{\sqrt{x}}$ by the product rule of limits.
[Let √x=z, so that z→0 as x→0]
= $\lim\limits_{z \to 0} \dfrac{\sin z}{z} \times \lim\limits_{x \to 0} \dfrac{1}{\sqrt{x}}$
= 1 × 1/0 using the formula limx→0 sinx/x =1.
= does not exist.
So the limit of sin(√x)/x does not exist as x→0.

The given limit can be written as follows:
$\lim\limits_{x \to 0} \dfrac{\sin \sqrt{x}}{2x}$ = $\dfrac{1}{2} \lim\limits_{x \to 0} \dfrac{\sin \sqrt{x}}{x}$
So by the above limit we prove, we conclude that the limit of sin(√x)/2x as x→0 does not exist.
