Limit Sine Pi 2A0Fa5
1. **State the problem:** Find the limit $$\lim_{x \to \pi} \frac{\sin x}{\pi - x}$$.
2. **Recall the formula and important rule:** This is a limit of the form $$\frac{\sin x}{\pi - x}$$ as $$x$$ approaches $$\pi$$. Notice that $$\sin \pi = 0$$, so the numerator approaches 0 and the denominator approaches 0, which is an indeterminate form $$\frac{0}{0}$$.
3. **Use substitution:** Let $$t = \pi - x$$. Then as $$x \to \pi$$, $$t \to 0$$.
4. **Rewrite the limit in terms of $$t$$:**
$$
\lim_{x \to \pi} \frac{\sin x}{\pi - x} = \lim_{t \to 0} \frac{\sin(\pi - t)}{t}
$$
5. **Use the identity:** $$\sin(\pi - t) = \sin t$$.
6. **Simplify the limit:**
$$
\lim_{t \to 0} \frac{\sin t}{t}
$$
7. **Recall the standard limit:**
$$
\lim_{t \to 0} \frac{\sin t}{t} = 1
$$
8. **Final answer:**
$$
\boxed{1}
