〖1/1算式〗
    作业：求算式 0.25*1396.12*(1+0.183)^2*((1-0.183)-160/1600)+0.5*1396.12*sin12.826 的值.
    题型：数学计算
    解:
          0.25*1396.12*(1+0.183)^2*((1-0.183)-160/1600)+0.5*1396.12*sin12.826
        =0.25*1396.12*1.183^2*((1-0.183)-160/1600)+0.5*1396.12*sin12.826
        =0.25*1396.12*1.183^2*(0.817-160/1600)+0.5*1396.12*sin12.826
        =0.25*1396.12*1.183^2*0.717+0.5*1396.12*sin12.826
        =0.25*1396.12*1.183^2*0.717+0.5*1396.12*0.256722

        =0.25*1396.12*1.399489*0.717+0.5*1396.12*0.256722
        =349.03*1.399489*0.717+0.5*1396.12*0.256722
        =488.463646*0.717+0.5*1396.12*0.256722
        =350.228434+0.5*1396.12*0.256722
        =350.228434+698.06*0.256722
        =350.228434+179.207359
        =529.435793
    答案:0.25*1396.12*(1+0.183)^2*((1-0.183)-160/1600)+0.5*1396.12*sin12.826=529.435793
