Step 1.1

Move the limit inside the trig function because sine is continuous.

$\frac{\sin (lim_{x \to 0} x^{2})}{x^{2}}$

Step 1.2

Move the exponent $2$ from $x^{2}$ outside the limit using the Limits Power Rule.

$\frac{\sin ({(lim_{x \to 0} x)}^{2})}{x^{2}}$

Step 2

Evaluate the limit of $x$ by plugging in $0$ for $x$ .

$\frac{\sin (0^{2})}{x^{2}}$

Step 3.1.1

Raising $0$ to any positive power yields $0$ .

$\frac{\sin (0)}{x^{2}}$

Step 3.1.2

The exact value of $\sin (0)$ is $0$ .

$\frac{0}{x^{2}}$

Step 3.2

Divide $0$ by $x^{2}$ .

$0$
