    作业：求算式 2/3*14.3*1000*3.14*0.2*0.2*0.4*sin(0.416*3.14)*sin(0.416*3.14)*sin(0.416*3.14) 的值.
    题型：数学计算
    解:
          2/3*14.3*1000*3.14*0.2*0.2*0.4*sin(0.416*3.14)*sin(0.416*3.14)*sin(0.416*3.14)
        =2/3*14.3*1000*3.14*0.2*0.2*0.4*sin1.30624*sin(0.416*3.14)*sin(0.416*3.14)
        =2/3*14.3*1000*3.14*0.2*0.2*0.4*sin1.30624*sin1.30624*sin(0.416*3.14)
        =2/3*14.3*1000*3.14*0.2*0.2*0.4*sin1.30624*sin1.30624*sin1.30624
        =2/3*14.3*1000*3.14*0.2*0.2*0.4*0.965209*sin1.30624*sin1.30624
        =2/3*14.3*1000*3.14*0.2*0.2*0.4*0.965209*0.965209*sin1.30624
        =2/3*14.3*1000*3.14*0.2*0.2*0.4*0.965209*0.965209*0.965209
        =0.666667*14.3*1000*3.14*0.2*0.2*0.4*0.965209*0.965209*0.965209
        =9.533338*1000*3.14*0.2*0.2*0.4*0.965209*0.965209*0.965209
        =9533.338*3.14*0.2*0.2*0.4*0.965209*0.965209*0.965209
        =29934.68132*0.2*0.2*0.4*0.965209*0.965209*0.965209
        =5986.936264*0.2*0.4*0.965209*0.965209*0.965209
        =1197.387253*0.4*0.965209*0.965209*0.965209
        =478.954901*0.965209*0.965209*0.965209
        =462.291581*0.965209*0.965209
        =446.207995*0.965209
        =430.683973
    答案:2/3*14.3*1000*3.14*0.2*0.2*0.4*sin(0.416*3.14)*sin(0.416*3.14)*sin(0.416*3.14)=430.683973
