# asecd

asecd(x)

Compute the inverse secant of `x`, where the output is in degrees

## Examples

In the Julia programming language, the function `asecd(x)` computes the inverse secant of `x` in degrees.

``````julia> asecd(1)
0.0

julia> asecd(-1)
180.0

julia> asecd(sqrt(2))
45.0``````

Here are some examples of how to use the `asecd` function:

1. Compute the inverse secant of 1:

``````julia> asecd(1)
0.0``````

The output is 0.0 degrees since the secant of 0 degrees is 1.

2. Compute the inverse secant of -1:

``````julia> asecd(-1)
180.0``````

The output is 180.0 degrees since the secant of 180 degrees is -1.

3. Compute the inverse secant of √2:
``````julia> asecd(sqrt(2))
45.0``````

The output is 45.0 degrees since the secant of 45 degrees is √2.

Common mistake example:

``````julia> asecd(2)
ERROR: DomainError with -2.0:
asin or acos: argument out of domain``````

In this example, the input `2` is out of the domain of the inverse secant function, which only accepts values between -1 and 1 inclusive. Make sure to provide valid input within the specified range to avoid such errors.
