Secant Values
1. **State the problem:** We need to fill in the missing values in the table for the function $y = -\sec(x)$ at $x = 0.1$ and $x = 0.2$ to 3 decimal places.
2. **Recall the function:** $y = -\sec(x) = -\frac{1}{\cos(x)}$.
3. **Calculate Box 1 ($x=0.1$):**
$$\cos(0.1) \approx 0.995$$
$$y = -\frac{1}{0.995} \approx -1.005$$
Rounded to 3 decimals: $-1.005$.
4. **Calculate Box 2 ($x=0.2$):**
$$\cos(0.2) \approx 0.980$$
$$y = -\frac{1}{0.980} \approx -1.020$$
Rounded to 3 decimals: $-1.020$.
5. **Summary:**
- Box 1 = $-1.005$
- Box 2 = $-1.020$
These values fit the pattern of the curve $y = -\sec(x)$ between $x=0$ and $x=0.5$.
