The correct Answer is:
To solve the problem, we need to find the value of \( \sin x \cdot \cot x \cdot \csc x \cdot \tan x \) given that \( \cos x = \frac{1}{3} \). ### Step-by-Step Solution: 1. **Identify the trigonometric identities**: - We know that: \[ \cot x = \frac{1}{\tan x} \] \[ \csc x = \frac{1}{\sin x} \] - Therefore, we can rewrite the expression \( \sin x \cdot \cot x \cdot \csc x \cdot \tan x \) using these identities. 2. **Rewrite the expression**: - Substitute the identities into the expression: \[ \sin x \cdot \cot x \cdot \csc x \cdot \tan x = \sin x \cdot \left(\frac{1}{\tan x}\right) \cdot \left(\frac{1}{\sin x}\right) \cdot \tan x \] 3. **Simplify the expression**: - Notice that \( \tan x \) and \( \cot x \) will cancel out: \[ = \sin x \cdot \frac{1}{\tan x} \cdot \frac{1}{\sin x} \cdot \tan x = 1 \] 4. **Final result**: - The final value of \( \sin x \cdot \cot x \cdot \csc x \cdot \tan x \) is: \[ = 1 \] ### Conclusion: Thus, the answer is \( 1 \).
