$\sec (0 °)$

Step 1

Find the value using the definition of secant.

$\sec (0 °) = \frac{hypotenuse}{adjacent}$

Step 2

Substitute the values into the definition.

$\sec (0 °) = \frac{1}{1}$

Step 3

Divide $1$ by $1$ .

$1$

Step 4

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