acsc
computes the element-wise inverse cosecant of the argument.
Syntax
y = acsc(x)
Arguments
- x
a real or complex array.
- y
a real or complex array.
Description
Computes the element-wise inverse cosecant of the argument. For real argument with absolute value greater than 1 the result is real.
The following equalities hold: acsc(z) == -acsc(-z) ==
asin(1/z) == %pi/2-asec(z) == %i*acsch(%i*z)
