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)
