A: To evaluate tan 5π/6, we need to use the unit circle and trigonometric identities. Using the definition of the tangent function, we can write tan 5π/6 = sin (5π/6) / cos (5π/6). From the unit circle, we know that sin (5π/6) = √3/2 and cos (5π/6) = -1/2. Therefore, tan 5π/6 = (√3/2) / (-1/2) = -√3.

  • Unit circle coordinates: The x and y coordinates of points on the unit circle are given by cos θ and sin θ, respectively.

    • A: To evaluate trigonometric functions using the unit circle, you can use the following steps:
