    作业：求算式 0.5*(200-116.67)*((104.16-14.58+30)*3.1415926/180)+0.5*116.67*14.58*3.1415926/180 的值.
    题型：数学计算
    解:
          0.5*(200-116.67)*((104.16-14.58+30)*3.1415926/180)+0.5*116.67*14.58*3.1415926/180
        =0.5*83.33*((104.16-14.58+30)*3.1415926/180)+0.5*116.67*14.58*3.1415926/180
        =0.5*83.33*(119.58*3.1415926/180)+0.5*116.67*14.58*3.1415926/180
        =0.5*83.33*2.087065+0.5*116.67*14.58*3.1415926/180
        =41.665*2.087065+0.5*116.67*14.58*3.1415926/180
        =86.957563+0.5*116.67*14.58*3.1415926/180
        =86.957563+58.335*14.58*3.1415926/180
        =86.957563+850.5243*3.1415926/180
        =86.957563+2672.000847/180
        =86.957563+14.844449
        =101.802012
    答案:0.5*(200-116.67)*((104.16-14.58+30)*3.1415926/180)+0.5*116.67*14.58*3.1415926/180=101.802012
