Background & Context
- ArcCot is the inverse cotangent function. For a real number , ArcCot[x] represents the radian angle measure (excluding 0) such that .
- ArcCot automatically threads over lists. For certain special arguments, ArcCot automatically evaluates to exact values. When given exact numeric expressions as arguments, ArcCot may be evaluated to arbitrary numeric precision. Operations useful for manipulation of symbolic expressions involving ArcCot include FunctionExpand, TrigToExp, TrigExpand, Simplify, and FullSimplify.
- ArcCot is defined for complex argument via . ArcCot[z] has a branch cut discontinuity in the complex plane.
- Related mathematical functions include Cot, ArcTan, and ArcCoth.
