Ruby | Math acosh() function Last Updated : 07 Jan, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report The acosh() is an inbuilt function in Ruby returns the inverse hyperbolic cosine of an angle given in radians. Syntax: Math.acosh(value) Parameters: The function accepts one mandatory parameter value which specifies the inverse hyperbolic angle in radian which should be greater or equal to 1. If the argument is less than 1, domain error is returned. Return Value: The function returns the inverse hyperbolic sine of the argument in radians which is in the range [0, inf]. Example 1: CPP #Ruby program for acosh() function #Assigning values val1 = 2 val2 = 877 val3 = 432 val4 = 43 #Prints the acosh() value puts Math.acosh(val1) puts Math.acosh(val2) puts Math.acosh(val3) puts Math.acosh(val4) Output: 1.3169578969248166 7.469653847888966 6.761571429209457 4.454212060602711 Example 2: CPP #Ruby program for acosh() function #Assigning values val1 = 20 val2 = 83 val3 = 332 val4 = 3 #Prints the acosh() value puts Math.acosh(val1) puts Math.acosh(val2) puts Math.acosh(val3) puts Math.acosh(val4) Output: 3.6882538673612966 5.111951496643704 6.498279881360139 1.762747174039086 Reference: https://devdocs.io/ruby~2.5/cmath#method-i-acosh Comment More infoAdvertise with us Next Article Ruby | Math acosh() function G gopaldave Follow Improve Article Tags : Ruby Ruby-Methods Ruby Collections Ruby Math-class Similar Reads Ruby | Math acos() function The acos() is an inbuilt function in Ruby which returns the inverse cosine of a number (argument) in radians.
