    作业：求算式 90+arctan(3.41)-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(2.93*3.41)-arctan(32.58*3.41) 的值.
    题型：数学计算
    解:
          90+arctan(3.41)-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(2.93*3.41)-arctan(32.58*3.41)
        =90+arctan3.41-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(2.93*3.41)-arctan(32.58*3.41)
        =90+arctan3.41-arctan1.705-arctan(3.41/5)-arctan(3.41/10)+arctan(2.93*3.41)-arctan(32.58*3.41)
        =90+arctan3.41-arctan1.705-arctan0.682-arctan(3.41/10)+arctan(2.93*3.41)-arctan(32.58*3.41)
        =90+arctan3.41-arctan1.705-arctan0.682-arctan0.341+arctan(2.93*3.41)-arctan(32.58*3.41)
        =90+arctan3.41-arctan1.705-arctan0.682-arctan0.341+arctan9.9913-arctan(32.58*3.41)
        =90+arctan3.41-arctan1.705-arctan0.682-arctan0.341+arctan9.9913-arctan111.0978
        =90+1.285539-arctan1.705-arctan0.682-arctan0.341+arctan9.9913-arctan111.0978
        =90+1.285539-1.040355-arctan0.682-arctan0.341+arctan9.9913-arctan111.0978
        =90+1.285539-1.040355-0.598543-arctan0.341+arctan9.9913-arctan111.0978
        =90+1.285539-1.040355-0.598543-0.328635+arctan9.9913-arctan111.0978
        =90+1.285539-1.040355-0.598543-0.328635+1.471041-arctan111.0978
        =90+1.285539-1.040355-0.598543-0.328635+1.471041-1.561795
        =91.285539-1.040355-0.598543-0.328635+1.471041-1.561795
        =90.245184-0.598543-0.328635+1.471041-1.561795
        =89.646641-0.328635+1.471041-1.561795
        =89.318006+1.471041-1.561795
        =90.789047-1.561795
        =89.227252
    答案:90+arctan(3.41)-arctan(3.41/2)-arctan(3.41/5)-arctan(3.41/10)+arctan(2.93*3.41)-arctan(32.58*3.41)=89.227252
