〖1/1算式〗
    作业：求算式 1466.8*(sin0.42*3.14*sin0.42*3.14*sin0.42*3.14)/3.14+258.51*(sin0.42*3.14+sin0.41*3.14)/3.14 的值.
    题型：数学计算
    解:
          1466.8*(sin0.42*3.14*sin0.42*3.14*sin0.42*3.14)/3.14+258.51*(sin0.42*3.14+sin0.41*3.14)/3.14
        =1466.8*2.098952/3.14+258.51*(sin0.42*3.14+sin0.41*3.14)/3.14
        =1466.8*2.098952/3.14+258.51*2.531998/3.14
        =3078.742794/3.14+258.51*2.531998/3.14
        =980.491336+258.51*2.531998/3.14
        =980.491336+654.546803/3.14
        =980.491336+208.454396
        =1188.945732
    答案:1466.8*(sin0.42*3.14*sin0.42*3.14*sin0.42*3.14)/3.14+258.51*(sin0.42*3.14+sin0.41*3.14)/3.14=1188.945732
    注：弧度制
