ArcSin

ArcSin[z]
gives the arc sine sin^(-1)(z) of the complex number z.
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • All results are given in radians.
  • For real z between -1 and 1, the results are always in the range -pi/2 to pi/2.
  • 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 z plane running from -∞ to -1 and +1 to +∞.
