cosh

cosh(x)

Compute hyperbolic cosine of x

Examples

In the Julia programming language, the function cosh(x) is used to compute the hyperbolic cosine of x.

julia> cosh(0)
1.0

julia> cosh(1)
1.5430806348152437

julia> cosh(2)
3.7621956910836314

Below are some common examples of its use:

1. Compute cosh for a single value:

   julia> cosh(0.5)
   1.1276259652063807

   This example calculates the hyperbolic cosine of the value 0.5.

2. Compute cosh for an array of values:

   julia> x = [0.1, 0.2, 0.3];
   julia> cosh(x)
   3-element Array{Float64,1}:
   1.0050041680558035
   1.0200667556190758
   1.0453385141288607

   The cosh function can be applied element-wise to an array.

3. Use cosh in mathematical expressions:

   julia> y = cosh(0.5) + cosh(1.2);
   julia> y
   4.930884149960785

   The cosh function can be used within larger mathematical expressions.

Common mistake example:

julia> cosh("hello")
ERROR: MethodError: no method matching cosh(::String)

In this example, the cosh function is applied to a string, which results in a MethodError. It is important to provide numerical values to the cosh function for it to work correctly.
