[1/1 Formula]
    Work: Calculate the value of equation 90+arctan(66.6*1.4)-arctan(888*1.4)-arctan(0.5*1.4) .
    Question type: Mathematical calculation
    Solution:
          90+arctan(66.6*1.4)-arctan(888*1.4)-arctan(0.5*1.4)
        =90+arctan93.24-arctan(888*1.4)-arctan(0.5*1.4)
        =90+arctan93.24-arctan1243.2-arctan(0.5*1.4)
        =90+arctan93.24-arctan1243.2-arctan0.7
        =90+1.560072-arctan1243.2-arctan0.7
        =90+1.560072-1.569992-arctan0.7
        =90+1.560072-1.569992-0.610726
        =91.560072-1.569992-0.610726
        =89.99008-0.610726
        =89.379354

    Answer:90+arctan(66.6*1.4)-arctan(888*1.4)-arctan(0.5*1.4)=89.379354
