[1/1 Formula]
    Work: Calculate the value of equation arctan(0.77*13)+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1) .
    Question type: Mathematical calculation
    Solution:
          arctan(0.77*13)+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)
        =arctan10.01+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)
        =arctan10.01+90-arctan1.3-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)
        =arctan10.01+90-arctan1.3-arctan0.13-arctan(0.02*13)-arctan(13*9.1)
        =arctan10.01+90-arctan1.3-arctan0.13-arctan0.26-arctan(13*9.1)
        =arctan10.01+90-arctan1.3-arctan0.13-arctan0.26-arctan118.3
        =1.471227+90-arctan1.3-arctan0.13-arctan0.26-arctan118.3
        =1.471227+90-0.915101-arctan0.13-arctan0.26-arctan118.3
        =1.471227+90-0.915101-0.129275-arctan0.26-arctan118.3
        =1.471227+90-0.915101-0.129275-0.254368-arctan118.3
        =1.471227+90-0.915101-0.129275-0.254368-1.562343
        =91.471227-0.915101-0.129275-0.254368-1.562343
        =90.556126-0.129275-0.254368-1.562343
        =90.426851-0.254368-1.562343
        =90.172483-1.562343
        =88.61014

    Answer:arctan(0.77*13)+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)=88.61014
