Secant Calculator

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.

Secant Formula

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
