tan

tan(x)

Compute tangent of x, where x is in radians

Examples

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)
   0.5463024898437905

   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}:
   0.10033467208545047
   0.2027100355086725
   0.30933624960962357

   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)
   -1.0296385570503641

   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.
