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)
