Short Answer

Expert verified

The exact value of the given expression is 1.

Step by step solution

Step 1. Given information.

The given expression is:

$\csc \frac{π}{2} + \cot \frac{π}{2}$

Step 2. Determine the exact value.

In the trigonometric table $\csc \frac{π}{2} = 1$ and $\cot \frac{π}{2} = 0$ . Substitute these values in the given expression.

$\begin{array}{rcl} \csc \frac{π}{2} + \cot \frac{π}{2} & = & (1) + (0) \\ = & 1 \end{array}$

Step 3. Conclusion.

The exact value of the given expression is 1.
