sin

sin(x)

Compute sine of x, where x is in radians

Examples

1. Calculate the sine of a single value:

   julia> x = 0.5;
   julia> sin(x)
   0.479425538604203

   This example computes the sine of the value 0.5 in radians.

2. Compute the sine of an array of values:

   julia> angles = [0.0, π/6, π/4, π/3, π/2];
   julia> sin(angles)
   5-element Array{Float64,1}:
   0.0
   0.5
   0.7071067811865476
   0.8660254037844386
   1.0

   It calculates the sine of each element in the angles array.

3. Evaluate the sine function for a matrix:

   julia> mat = [0.0  π/4;
                π/3 π/2];
   julia> sin(mat)
   2×2 Array{Float64,2}:
   0.0              0.7071067811865476
   0.8660254037844386  1.0

   In this example, the sin function is applied element-wise to each entry of the matrix.

Common mistake example:

julia> sin("1.0")
ERROR: MethodError: no method matching sin(::String)

In this case, the argument provided to the sin function is of type String, which is not compatible. Ensure that the input to sin is a numeric type, such as Float64 or Int.
