Returns the inverse secant of the given angle.
ASEC(Angle)
Angle is the angle in radians for which you want the inverse secant.
The mathematical definition of inverse secant is :
Let Atn(x) be inverse tangent of angle x in radians. Let Sgn(x) be the sign of x in radians.
If the angle is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.
