gives the inverse haversine function .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • The inverse haversine function is defined by .
  • All results are given in radians.
  • For real between and , the results are always in the range to .
  • InverseHaversine[z] has branch cut discontinuities in the complex plane running from to and to .
  • InverseHaversine can be evaluated to arbitrary numerical precision.
  • InverseHaversine automatically threads over lists.
