[1/1 Formula]
    Work: Calculate the value of equation 90-arctan(0.1*9.7)-arctan(0.2*9.7) .
    Question type: Mathematical calculation
    Solution:
          90-arctan(0.1*9.7)-arctan(0.2*9.7)
        =90-arctan0.97-arctan(0.2*9.7)
        =90-arctan0.97-arctan1.94
        =90-0.770171-arctan1.94
        =90-0.770171-1.094854
        =89.229829-1.094854
        =88.134975

    Answer:90-arctan(0.1*9.7)-arctan(0.2*9.7)=88.134975
