Answer & Solution
Correct Answer
(D) \(\sqrt{3}+\cot \left(\frac{\pi}{3}-\theta\right)\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \tan \left(-\frac{23 \pi}{3}\right)-\cot \left(\theta-\frac{13 \pi}{3}\right) \\ & =-\tan \left(7 \pi+\frac{2 \pi}{3}\right)+\cot \left(4 \pi+\left(\frac{\pi}{3}-\theta\right)\right) \\ & =-\tan \frac{2 \pi}{3}+\cot \left(\frac{\pi}{3}-\theta\right) \\ & =-\tan…
