cscd

Computes the element-wise cosecant of the argument given in degree.

Calling Sequence

x = cscd(x)

Arguments

:x Real or complex array. : :x Real or complex array. :

Description

The entries of y are the cosecant 1/sin of the entries of x given in degree. The results are real and in ]-%inf -1] U [1 %inf[. For entries equal to n*180 with n integer, the result is infinite (or an error depending on ieee mode). For entries equal to n*90`with `n integer and odd the result is exactly 1 or -1.

Examples

`csc`_(%pi/4)
cscd(90)
