〖1/1算式〗
    作业：求算式 0.32*14.3*1000*3.1416*0.375*0.375*(1-sin(360*0.32)/(2*3.1415926*0.32))+(2*0.32-1.25)*300*5.1 的值.
    题型：数学计算
    解:
          0.32*14.3*1000*3.1416*0.375*0.375*(1-sin(360*0.32)/(2*3.1415926*0.32))+(2*0.32-1.25)*300*5.1
        =0.32*14.3*1000*3.1416*0.375*0.375*(1-sin115.2/(2*3.1415926*0.32))+(2*0.32-1.25)*300*5.1
        =0.32*14.3*1000*3.1416*0.375*0.375*(1-sin115.2/2.010619)+(2*0.32-1.25)*300*5.1
        =0.32*14.3*1000*3.1416*0.375*0.375*0.571345+(2*0.32-1.25)*300*5.1
        =0.32*14.3*1000*3.1416*0.375*0.375*0.571345+(-0.61)*300*5.1
        =4.576*1000*3.1416*0.375*0.375*0.571345+(-0.61)*300*5.1
        =4576*3.1416*0.375*0.375*0.571345+(-0.61)*300*5.1
        =14375.9616*0.375*0.375*0.571345+(-0.61)*300*5.1
        =5390.9856*0.375*0.571345+(-0.61)*300*5.1
        =2021.6196*0.571345+(-0.61)*300*5.1
        =1155.04225+(-0.61)*300*5.1
        =1155.04225+(-183)*5.1
        =1155.04225+(-933.3)
        =221.74225
    答案:0.32*14.3*1000*3.1416*0.375*0.375*(1-sin(360*0.32)/(2*3.1415926*0.32))+(2*0.32-1.25)*300*5.1=221.74225
