Contributed by: Paco Jain (Wolfram Research)

ResourceFunction["ArcSecDegree"][x]

computes the inverse secant of x in degrees.

Details and Options

Mathematical function, suitable for both symbolic and numerical manipulation.
ResourceFunction["ArcSecDegree"][x] is undefined for x = 0.
ResourceFunction["ArcSecDegree"][x] is undefined in the range -1 to 1.
For x outside the interval -1 to 1, ResourceFunction["ArcSecDegree"][x] always in the range 0 to 180 excluding 90.
For certain special arguments, ResourceFunction["ArcSecDegree"] automatically evaluates to exact values.
ResourceFunction["ArcSecDegree"] can be evaluated to arbitrary numerical precision.
ResourceFunction["ArcSecDegree"] automatically threads over lists.

Examples

Basic Examples (2)
