Compute the inverse hyperbolic secant of x


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

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

    julia> asech(0.2)

    This example calculates the inverse hyperbolic secant of 0.2.

  2. Handle edge cases:

    julia> asech(1)

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

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

    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.
