### Trigonometric Expression Matching Exercise

**Instructions:**
Match each of the trigonometric expressions below with the equivalent non-trigonometric function from the list provided. Enter the appropriate letter (A, B, C, D, or E) in each blank.

**Trigonometric Expressions:**
- A. \(\tan(\sin^{-1}(x/2))\)
- B. \(\cos(\sin^{-1}(x/2))\)
- C. \((1/2) \sin(2 \sin^{-1}(x/2))\)
- D. \(\sin(\tan^{-1}(x/2))\)
- E. \(\cos(\tan^{-1}(x/2))\)

**Non-Trigonometric Functions:**

1. \(\frac{x}{\sqrt{4 + x^2}}\)

2. \(\frac{\sqrt{4 - x^2}}{x}\)

3. \(\sqrt{\frac{4}{4 + x^2}}\)

4. \(\frac{x\sqrt{4 + x^2}}{4}\)

5. \(\frac{\sqrt{4 - x^2}}{2}\)

**Objective:**
Determine the correct match between the trigonometric expression and the non-trigonometric function. Use your knowledge of inverse trigonometric identities and properties to find the correct pairings.
