BUILT-IN MATHEMATICA SYMBOL

ArcCsc

ArcCsc[z]
gives the arc cosecant

of the complex number

.

MORE INFORMATION

Mathematical function, suitable for both symbolic and numerical manipulation.

All results are given in radians.

For real z outside the interval to , the results are always in the range to , excluding 0.

For certain special arguments, ArcCsc automatically evaluates to exact values.

ArcCsc can be evaluated to arbitrary numerical precision.

ArcCsc automatically threads over lists.

ArcCsc[z] has a branch cut discontinuity in the complex plane running from to .
