Answer

Final Answer: \(\cot \frac{\pi}{12} = \tan \frac{5\pi}{12} = \boxed{3.732}\)

Steps

Step 1 :Write the function in terms of the cofunction of a complementary angle.

Step 2 :The cotangent function is the reciprocal of the tangent function.

Step 3 :The complementary angle of \(\frac{\pi}{12}\) is \(\frac{\pi}{2} - \frac{\pi}{12} = \frac{5\pi}{12}\).

Step 4 :Therefore, \(\cot(\frac{\pi}{12})\) is equivalent to \(\tan(\frac{5\pi}{12})\).

Step 5 :Final Answer: \(\cot \frac{\pi}{12} = \tan \frac{5\pi}{12} = \boxed{3.732}\)
