Ruby - Math.acosh() Method
The Ruby Math.acosh() method returns inverse hyperbolic cosine of a value. The inverse hyperbolic cosine of x is defined as:
Syntax
Math.acosh(x)
Parameters
x |
Specify the value equal to or greater than 1. |
Return Value
Returns the inverse hyperbolic cosine of a value. If x is less than 1, DomainError is thrown.
Example:
In the example below, Math.acosh() method is used to find out the inverse hyperbolic cosine of a value.
puts "Math.acosh(1) = #{Math.acosh(1)}"
puts "Math.acosh(1.5) = #{Math.acosh(1.5)}"
puts "Math.acosh(2) = #{Math.acosh(2)}"
puts "Math.acosh(4) = #{Math.acosh(4)}"
The output of the above code will be:
Math.acosh(1) = 0.0 Math.acosh(1.5) = 0.9624236501192069 Math.acosh(2) = 1.3169578969248166 Math.acosh(4) = 2.0634370688955608
