〖1/1算式〗
    作业：求算式 100000×((0.005×(1-cos(83/62500)))/cos(83/62500))/(tan(83/62500)-(83/62500)) 的值.
    题型：数学计算
    解:
          100000×((0.005×(1-cos(83/62500)))/cos(83/62500))/(tan(83/62500)-(83/62500))
        =100000×((0.005×(1-cos0.001328))/cos(83/62500))/(tan(83/62500)-(83/62500))
        =100000×((0.005×0.000001)/cos(83/62500))/(tan(83/62500)-(83/62500))
        =100000×(0/cos(83/62500))/(tan(83/62500)-(83/62500))
        =100000×(0/cos0.001328)/(tan(83/62500)-(83/62500))
        =100000×0/(tan(83/62500)-(83/62500))
        =100000×0/(tan0.001328-(83/62500))
        =100000×0/(tan0.001328-0.001328)
        =100000×0/0
        =0/0
        =-nan
    答案:100000×((0.005×(1-cos(83/62500)))/cos(83/62500))/(tan(83/62500)-(83/62500))=-nan
    注：弧度制
