ACOT

ACOT: Returns the angle in radians whose cotangent is the input value.

Summary

ACOT maps real inputs to principal angles in (0, PI()).

Remarks

  • Domain: accepts any real number, including 0.
  • Radians: output is in (0, PI()), with ACOT(0) = PI()/2.
  • Errors: no function-specific domain errors are produced.
