$- \csc^{2} (\frac{5 π}{6})$

Step 1

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

$- \csc^{2} (\frac{π}{6})$

Step 2

The exact value of $\csc (\frac{π}{6})$ is $2$ .

$- 2^{2}$

Step 3

Raise $2$ to the power of $2$ .

$- 1 \cdot 4$

Step 4

Multiply $- 1$ by $4$ .

$- 4$
