# asin

asin(x)

Compute the inverse sine of `x`, where the output is in radians

## Examples

In the Julia programming language, the `asin` function is used to compute the inverse sine of a given value `x`, where the output is in radians. Here are some examples of how to use the `asin` function:

1. Compute the inverse sine of a number:

``````julia> asin(0.5)
0.5235987755982989``````

This example calculates the inverse sine of `0.5`, which is approximately `0.5235987755982989` radians.

2. Handle negative input:

``````julia> asin(-0.8)
-0.9272952180016122``````

It computes the inverse sine of `-0.8`, which results in `-0.9272952180016122` radians.

3. Use variables as input:
``````julia> x = 0.707;
julia> asin(x)
0.7753974966107531``````

Here, the variable `x` is used as the input to compute the inverse sine.

Common mistake example:

``````julia> asin(2)
ERROR: DomainError with -2.0:
asin will only return values in the range [-π/2, π/2]``````

In this example, the input value `2` is outside the valid range (`[-1, 1]`) for the `asin` function. It's important to ensure that the input value falls within the appropriate domain to avoid such errors.
