    作业：求算式 90-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(3.41)+arctan(2.93*3.41)-arctan(34.1*3.41) 的值.
    题型：数学计算
    解:
          90-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(3.41)+arctan(2.93*3.41)-arctan(34.1*3.41)
        =90-arctan1.705-arctan(3.41/5)-arctan(3.41/10)+arctan(3.41)+arctan(2.93*3.41)-arctan(34.1*3.41)
        =90-arctan1.705-arctan0.682-arctan(3.41/10)+arctan(3.41)+arctan(2.93*3.41)-arctan(34.1*3.41)
        =90-arctan1.705-arctan0.682-arctan0.341+arctan(3.41)+arctan(2.93*3.41)-arctan(34.1*3.41)
        =90-arctan1.705-arctan0.682-arctan0.341+arctan3.41+arctan(2.93*3.41)-arctan(34.1*3.41)
        =90-arctan1.705-arctan0.682-arctan0.341+arctan3.41+arctan9.9913-arctan(34.1*3.41)
        =90-arctan1.705-arctan0.682-arctan0.341+arctan3.41+arctan9.9913-arctan116.281
        =90-1.040355-arctan0.682-arctan0.341+arctan3.41+arctan9.9913-arctan116.281
        =90-1.040355-0.598543-arctan0.341+arctan3.41+arctan9.9913-arctan116.281
        =90-1.040355-0.598543-0.328635+arctan3.41+arctan9.9913-arctan116.281
        =90-1.040355-0.598543-0.328635+1.285539+arctan9.9913-arctan116.281
        =90-1.040355-0.598543-0.328635+1.285539+1.471041-arctan116.281
        =90-1.040355-0.598543-0.328635+1.285539+1.471041-1.562197
        =88.959645-0.598543-0.328635+1.285539+1.471041-1.562197
        =88.361102-0.328635+1.285539+1.471041-1.562197
        =88.032467+1.285539+1.471041-1.562197
        =89.318006+1.471041-1.562197
        =90.789047-1.562197
        =89.22685
    答案:90-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(3.41)+arctan(2.93*3.41)-arctan(34.1*3.41)=89.22685
