gives the arc sine of the complex number .


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