**Exploration 1: Finding Inverse Trig Functions of Trig Functions**

In the right triangle shown to the right, the angle \( \theta \) is measured in radians.

1. Find \( \tan \theta \).
2. Find \( \tan^{-1} x \).
3. Find the hypotenuse of the triangle as a function of \( x \).
4. Find \( \sin (\tan^{-1} x) \) as a ratio involving no trig functions.
5. Find \( \sec (\tan^{-1} x) \) as a ratio involving no trig functions.
6. If \( x < 0 \), then \( \tan^{-1} x \) is a negative angle in the fourth quadrant (Figure 4.86). Verify that your answers to parts (4) and (5) are still valid in this case.

**Diagram Explanation:**

The diagram is a right triangle with an angle \( \theta \), opposite side labeled as \( x \), and adjacent side labeled as 1.
