gives the arc cotangent of the complex number .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • All results are given in radians.
  • For real , the results are always in the range to , excluding 0.
  • For certain special arguments, ArcCot automatically evaluates to exact values.
  • ArcCot can be evaluated to arbitrary numerical precision.
  • ArcCot automatically threads over lists.
  • ArcCot[z] has a branch cut discontinuity in the complex plane running from to .
