Contributed by: Paco Jain (Wolfram Research)

ResourceFunction["ArcCosDegree"][x]

computes the inverse cosine of x in degrees.

Details and Options

ArcCosDegree is a mathematical function, suitable for both symbolic and numerical manipulation.
ArcCosDegree[x] is undefined outside the range -1 to 1.
ArcCosDegree[x] always returns a value in the range 0 to 180.
For certain special arguments, ArcCosDegree automatically evaluates to exact values.
ArcCosDegree can be evaluated to arbitrary numerical precision.
ArcCosDegree automatically threads over lists.

Examples
