        =91.517513+1.231356-0.982794-0.14889-0.291457-1.568663-0.340234
        =92.748869-0.982794-0.14889-0.291457-1.568663-0.340234
        =91.766075-0.14889-0.291457-1.568663-0.340234
        =91.617185-0.291457-1.568663-0.340234
        =91.325728-1.568663-0.340234
        =89.757065-0.340234
        =89.416831
    答案:90+arctan(15*1.25)+arctan(15*0.1888)-arctan(15*0.1)-arctan(15*0.01)-arctan(15*0.02)-arctan(15*31.25)-arctan(15*0.0236)=89.416831
