1. **State the problem:** Determine if the expression $\frac{2\cos x}{1} \times \frac{1}{\cos x}$ equals 2.
2. **Write the expression:**
$$\frac{2\cos x}{1} \times \frac{1}{\cos x}$$
3. **Multiply the fractions:**
$$\frac{2\cos x}{1} \times \frac{1}{\cos x} = \frac{2\cos x \times 1}{1 \times \cos x} = \frac{2\cos x}{\cos x}$$
4. **Simplify by canceling $\cos x$:**
$$\frac{2\cancel{\cos x}}{\cancel{\cos x}} = 2$$
5. **Conclusion:** The expression simplifies to 2, so yes, it equals 2.
This works as long as $\cos x \neq 0$ to avoid division by zero.
