cscd
сomputes the element-wise cosecant of the argument given in degree
Syntax
y = cscd(x)
Arguments
- x
a real or complex array.
- y
a real or complex array.
Description
The entries of y
are the cosecant
1/sin(x)
of the entries of x
given in
degree. The results are real and in ]-∞,-1] ∪ [1,∞[
.
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)
