Deriving a Secant and Cosecant

Written by Allen Wyatt (last updated July 30, 2022)
This tip applies to Excel 97, 2000, 2002, and 2003


Excel includes many built-in functions that allow you to use a wide range of trigonometric functions. Two that are not included, however, are functions for determining a secant and a cosecant. Let's assume that an angle value, in radians, is stored in cell B7. If you need to know the secant of the angle, you can use the following formula:

=1/COS(B7)

Likewise, if you need to know the cosecant of the angle, the following formula will do the trick:

=1/SIN(B7)
