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.
