SEC
Formulas / SECCalculate the secant of an angle.
=SEC(angle)
- angle - required, the angle in radians
Examples
SEC(PI()/6)The SEC function can be used to calculate the secant of an angle in radians. For example, the following formula returns 1.514, the secant of 30 degrees.
SEC(60*PI()/180)The SEC function can also be used to calculate the secant of an angle in degrees. For example, the following formula returns 1.154, the secant of 60 degrees.
SEC(RADIANS(60))The RADIANS function can be used in conjunction with the SEC function to calculate the secant of an angle in degrees. For example, the following formula returns 1.154, the secant of 60 degrees.
Summary
The SEC function is used to calculate the secant of an angle in radians. It requires a number argument to be passed as an input.
- The SEC function is the reciprocal of COS, and calculates the secant of an angle in radians.
- In terms of right-triangle trigonometry, the secant of an angle is the ratio of the length of the hypotenuse to the length of the adjacent side.
