This function returns the hyperbolic secant of the specified angle.
SECH(angle)
This function can take any real number as an argument. The angle argument is the angle in radians for which you want the hyperbolic secant.
The absolute value of angle must be less than 2^27.
Accepts numeric data. Returns numeric data.
SECH(30) gives the result 1.87E-13
SECH(45) gives the result 5.73E-20
