$\csc (270)$

Step 1

Find the value using the definition of cosecant.

$\csc (270) = \frac{hypotenuse}{opposite}$

Step 2

Substitute the values into the definition.

$\csc (270) = \frac{1}{- 1}$

Step 3

Divide $1$ by $- 1$ .

$- 1$

Step 4

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
