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.
