take the arcsine of a number in ruby

To take the arcsine of a number in Ruby, you need to use the asin method provided by Ruby's built-in Math module. Here's an example:

main.rb
num = 0.5
result = Math.asin(num)
puts result
46 chars
4 lines

In this example, we are taking the arcsine of the number 0.5 using the asin method from the Math module. The result will be in radians and will be printed to the console using the puts method.

Note: The asin method expects the input value to be in the range of -1 to 1. If the input is outside this range, the method will raise a DomainError.
