Secant Calculator





Formula

The formula to calculate the secant of an angle is:

\[ \sec X = \frac{H}{A} \]

Where:

The secant can also be calculated using the inverse of the cosine:

\[ \sec X = \frac{1}{\cos X} \]

Secant Definition

The secant is defined as the inverse of the cosine of a value. It is the ratio of the length of the hypotenuse to the length of the adjacent side in a right-angled triangle.

Example Calculation

Let's assume the following values:

Step 1: Calculate the Secant (sec X):

\[ \sec X = \frac{10}{8} = 1.25 \]

The secant of the angle is 1.25.
