Ruby | Math asin() function Last Updated : 04 Dec, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report The asin() is an inbuilt function in Ruby returns the arc sine of a number means give a sin value to this function it will return the angle in radian corresponding to that value. The value passed is in between -1 and +1. Syntax: Math.asin(value) Parameters: The function accepts one mandatory parameter value whose corresponding angle we have to find. Return Value: It returns the angle in radians which in range -pi/2 to +pi/2. Example 1: Ruby #Ruby program for asin() function #Assigning values val1 = 1 val2 = 0.5 val3 = -1 val4 = -0.9 #Prints the asin() value puts Math.asin(val1) puts Math.asin(val2) puts Math.asin(val3) puts Math.asin(val4) Output: 1.5707963267948966 0.5235987755982989 -1.5707963267948966 -1.1197695149986342 Example 2: Ruby #Ruby program for asin() function #Assigning values val1 = 0.87 val2 = 0.67 val3 = -0.679 val4 = -0.564 #Prints the asin() value puts Math.asin(val1) puts Math.asin(val2) puts Math.asin(val3) puts Math.asin(val4) Output: 1.0552023205488061 0.7342087874533589 -0.746399633896421 -0.59922176813665 Reference: https://devdocs.io/ruby~2.5/math#method-c-asin Comment More infoAdvertise with us Next Article Ruby | Math asin() function G gopaldave Follow Improve Article Tags : Ruby Ruby-Methods Ruby Collections Ruby Math-class Similar Reads Ruby | Math asinh() function The asinh() is an inbuilt function in Ruby returns the inverse hyperbolic sine of an angle given in radians.
