Answer

-\sqrt{3} Explanation 1. Determine the angle in standard position \frac{4\pi}{3} is in the third quadrant. 2. Calculate reference angle Reference angle is \pi - \frac{4\pi}{3} = \frac{\pi}{3}. 3. Evaluate cotangent in the third quadrant In the third quadrant, cotangent is negative. **cot(\frac{\pi}{3}) = \sqrt{3}**. 4. Apply sign for the third quadrant Since cotangent is negative in the third quadrant, cot(\frac{4\pi}{3}) = -\sqrt{3}.

Explanation

1. Determine the angle in standard position<br /> $\frac{4\pi}{3}$ is in the third quadrant.<br /><br />2. Calculate reference angle<br /> Reference angle is $\pi - \frac{4\pi}{3} = \frac{\pi}{3}$.<br /><br />3. Evaluate cotangent in the third quadrant<br /> In the third quadrant, cotangent is negative. **cot($\frac{\pi}{3}$) = $\sqrt{3}$**.<br /><br />4. Apply sign for the third quadrant<br /> Since cotangent is negative in the third quadrant, $cot(\frac{4\pi}{3}) = -\sqrt{3}$.
