Step 1. Given information.

The given expression is:

$\sec π - \csc \frac{π}{2}$

Step 2. Determine the exact value.

In the trigonometric table $\sec π = - 1$ and $\csc \frac{π}{2} = 1$ . Substitute these values in the given expression.

$\begin{array}{rcl} \sec π - \csc \frac{π}{2} & = & (- 1) - (1) \\ = & - 2 \end{array}$

Step 3. Conclusion.

The exact value of the given expression is $- 2$ .
