Calculate the secant of an angle of a right triangle. Enter the angle to calculate the ratio of the hypotenuse divided by the adjacent side of the triangle.
Sec X = H/A
- Where X is an angle in degrees or radians
- H is the length of the hypotenuse
- A is the length of the side adjacent to that hypotenuse
The secant can also be calculated using the inverse of the cosine.
sec x = 1 / cos x
