cscd

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*90with n integer and odd the result is exactly 1 or -1.

Examples

csc(%pi/4)
cscd(90)
