ArcSecDegree

Contributed by: Paco Jain (Wolfram Research)

Computes the inverse secant of a number and returns a result in degrees

ResourceFunction["ArcSecDegree"][x]

computes the inverse secant of x in degrees

Details and Options

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

Examples

Basic Examples

Compute the inverse secant of a number:

In[1]:=
ResourceFunction["ArcSecDegree"][1]
Out[1]=

Plot over a given range of values:

In[2]:=
Plot[ResourceFunction["ArcSecDegree"][x], {x, -5, 5}]
Out[2]=

Scope

Evaluate numerically:

In[3]:=
ResourceFunction["ArcSecDegree"][43.1]
Out[3]=

Evaluate to high precision:

In[4]:=
N[ResourceFunction["ArcSecDegree"][26], 50]
Out[4]=
