Evaluate `lim_(x to 0) (sinx-2)/(cosx-1).`

Explanation

To evaluate the limit \( \lim_{x \to 0} \frac{\sin x - 2}{\cos x - 1} \), we will follow these steps:

### Step 1: Substitute \( x = 0 \)
First, we substitute \( x = 0 \) into the expression to check if we can directly evaluate the limit.

\[ \sin(0) - 2 = 0 - 2 = -2 \]
