Hi there!


\large\boxed{tan\text{ } ((-\pi )/(6))}

**Recall that tangent is Opposite / Adjacent**

tan (5π / 6) according to the unit circle equals -1 / √3. We can go through each choice and eliminate:

  • tan (-5π / 6) is in the third quadrant which would mean that the value would be positive 1 / √3. This choice is incorrect.

  • tan (7π / 6) is the same as tan (-5π / 6), which is positive 1 / √3. This choice is incorrect.

  • cot (5π / 6) is the reciprocal of tan 5π / 6, which is incorrect.

  • tan (-π / 6) is equal to -1 / √3. This choice is correct.

Therefore, the correct choice is tan (-π / 6).
