cotd
element-wise cotangent function, argument in degree
Calling Sequence
y = cotd(x)
Arguments
- x
a real array.
- y
a real array with same dimensions as
x
.
Description
The entries of y
are the cotangents of the
corresponding entries of x
supposed to be given in
degree. t=cos(x)./sin(x)
. For entries equal to
n*180
with n
integers the results
are infinite, whereas cotg(n*%pi)
is large but finite
because %pi
cannot be represented exactly. For entries
equal to n*90
with n
integers and
odd the results are exactly 0
.
Examples
x=[30 45 60 90]; cotd(x)
