cotd

cotangent

Calling Sequence

y=cotd(x)

Arguments

x

Real array.

y

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)
