csc

csc(x)

Compute the cosecant of x, where x is in radians

Examples

1. Compute the cosecant of a single value:

   julia> csc(1.0)
   1.1883951057781212

   This example calculates the cosecant of 1.0 radians.

2. Compute the cosecant of an array of values:

   julia> angles = [0.0, π/6, π/4, π/3, π/2];
   julia> csc.(angles)
   5-element Array{Float64,1}:
   Inf
   2.0
   1.4142135623730951
   1.7320508075688772
   1.0

   It computes the cosecant of each element in the angles array.

3. Compute the cosecant of a negative value:

   julia> csc(-2.0)
   -1.0997501702946164

   This example calculates the cosecant of -2.0 radians.

Common mistake example:

julia> csc([0, π/2, π])
ERROR: MethodError: no method matching csc(::Array{Float64,1})

In this example, an array of angles is passed to the csc function. However, the csc function does not support arrays as input. It can only compute the cosecant of individual values. To calculate the cosecant of multiple angles, you can use broadcasting (.) as shown in example 2.
