# ArcSinh

 ArcSinh[z]gives the inverse hyperbolic sine of the complex number .
• Mathematical function, suitable for both symbolic and numerical manipulation.
• For certain special arguments, ArcSinh automatically evaluates to exact values.
• ArcSinh can be evaluated to arbitrary numerical precision.
• ArcSinh automatically threads over lists.
• ArcSinh[z] has branch cut discontinuities in the complex plane running from to and to .
