Inverse secant in degrees
Syntax
Description
returns the
inverse secant (sec-1) of the elements of
Y
= asecd(X
)X
in degrees. The function accepts both real and complex inputs.
For real values of
X
in the intervals [-∞, -1] and [1, ∞],asecd(X)
returns values in the interval [0, 180].For real values of
X
in the interval (-1, 1) and for complex values ofX
,asecd(X)
