Compute tangent of x, where x is in radians


In the Julia programming language, the function tan(x) is used to compute the tangent of x, where x is in radians.

  1. Compute tangent of an angle:

    julia> tan(0.5)

    This example computes the tangent of the angle 0.5 radians.

  2. Compute tangent of multiple angles:

    julia> angles = [0.1, 0.2, 0.3];
    julia> tan.(angles)
    3-element Array{Float64,1}:

    It computes the tangent of each angle in the array angles using broadcast syntax tan.(angles).

  3. Compute tangent of a negative angle:
    julia> tan(-0.8)

    It computes the tangent of a negative angle.

Common mistake example:

julia> tan(pi/2)
ERROR: DomainError with tan, pi/2 is not a valid argument

In this example, pi/2 is not a valid argument for the tangent function because the tangent of pi/2 is undefined. Ensure that the input value is within the valid domain of the tangent function to avoid such errors.
