[1/1 Formula]
    Work: Calculate the value of equation 90+arctan(0.36*4.4)-arctan(4.4)-arctan(0.12*4.4) .
    Question type: Mathematical calculation
    Solution:
          90+arctan(0.36*4.4)-arctan(4.4)-arctan(0.12*4.4)
        =90+arctan1.584-arctan(4.4)-arctan(0.12*4.4)
        =90+arctan1.584-arctan4.4-arctan(0.12*4.4)
        =90+arctan1.584-arctan4.4-arctan0.528
        =90+1.00767-arctan4.4-arctan0.528
        =90+1.00767-1.34732-arctan0.528
        =90+1.00767-1.34732-0.485796
        =91.00767-1.34732-0.485796
        =89.66035-0.485796
        =89.174554

    Answer:90+arctan(0.36*4.4)-arctan(4.4)-arctan(0.12*4.4)=89.174554
