# cscd

cscd(x)

Compute the cosecant of `x`, where `x` is in degrees

## Examples

In the Julia programming language, the `cscd(x)` function computes the cosecant of `x` where `x` is in degrees.

``````julia> cscd(30)
1.1547005383792515``````

Here are some common examples of its use:

1. Compute the cosecant of an angle in degrees:

``````julia> cscd(45)
1.4142135623730951``````

This example calculates the cosecant of 45 degrees.

2. Calculate the cosecant of multiple angles:

``````julia> angles = [30, 60, 90, 120];
julia> cscd.(angles)
4-element Array{Float64,1}:
1.1547005383792515
1.7320508075688772
Inf
-1.7320508075688772``````

It computes the cosecant of each angle in the `angles` array.

3. Handle zero as an input:
``````julia> cscd(0)
Inf``````

Since the sine of 0 degrees is 0, the cosecant becomes infinite.

Common mistake example:

``````julia> cscd(90)
ERROR: DomainError with -3.0413812651491097e16:
cscd: argument must be finite and real``````

In this example, the input angle of 90 degrees leads to a domain error because the cosecant of 90 degrees is undefined. Ensure that the input values are within the valid domain to avoid such errors.
