Final Answer: The solution to the equation \(\cot \theta=-\frac{1}{6}\) for \(\frac{3 \pi}{2}<\theta<2 \pi\) is \(\boxed{8.0191}\) radians

Steps

Step 1 :Rewrite the equation as \(\tan \theta=-6\)

Step 2 :Use the arctan function to find the angle whose tangent is -6

Step 3 :Since the arctan function returns a value in the interval \(-\frac{\pi}{2}<\theta<\frac{\pi}{2}\), add \(\pi\) to the result to get an angle in the desired interval

Step 4 :Convert the result to radians and add \(2\pi\) to it until it falls within the desired interval \(\frac{3 \pi}{2}<\theta<2 \pi\)

Step 5 :Final Answer: The solution to the equation \(\cot \theta=-\frac{1}{6}\) for \(\frac{3 \pi}{2}<\theta<2 \pi\) is \(\boxed{8.0191}\) radians
