MCQ
Choose the correct answer. $\lim\limits_{\text{x} \rightarrow \pi}\frac{\sin\text{x}}{\text{x}-\pi}$ is:
  • A
    $1$
  • B
    $2$
  • ✓
    $-1$
  • D
    $-2$
✓

Answer

Correct option: C.
$-1$
Given, $\lim\limits_{\text{x} \rightarrow \pi}\frac{\sin\text{x}}{\text{x}-\pi}$
$=\lim\limits_{\text{x} \rightarrow\pi}\frac{\sin(\pi)-\text{x}}{-(\pi-\text{x})}$
$=-1$
