[1/1 Formula]
    Work: Calculate the value of equation sqrt(6)*arctan(sqrt((1.5^2-1)/6))-arctan(sqrt(1.5^2-1))-0.468 .
    Question type: Mathematical calculation
    Solution:
          sqrt(6)*arctan(sqrt((1.5^2-1)/6))-arctan(sqrt(1.5^2-1))-0.468
        =sqrt6*arctan(sqrt((1.5^2-1)/6))-arctan(sqrt(1.5^2-1))-0.468
        =sqrt6*arctan(sqrt(1.25/6))-arctan(sqrt(1.5^2-1))-0.468
        =sqrt6*arctan(sqrt0.208333)-arctan(sqrt(1.5^2-1))-0.468
        =sqrt6*arctan0.456435-arctan(sqrt(1.5^2-1))-0.468
        =sqrt6*arctan0.456435-arctan(sqrt1.25)-0.468
        =sqrt6*arctan0.456435-arctan1.118034-0.468
        =2.44949*arctan0.456435-arctan1.118034-0.468
        =2.44949*0.428192-arctan1.118034-0.468
        =2.44949*0.428192-0.841069-0.468
        =1.048852-0.841069-0.468
        =0.207783-0.468
        =-0.260217

    Answer:sqrt(6)*arctan(sqrt((1.5^2-1)/6))-arctan(sqrt(1.5^2-1))-0.468=-0.260217
