    题型：数学计算
    解:
          2/3*14300*0.5/4*(sin(180*0.245))^3+300*6.283*0.44/3.14159*(sin(180*0.245)+sin(180*(1.25-0.245*2)))
        =2/3*14300*0.5/4*(sin44.1)^3+300*6.283*0.44/3.14159*(sin(180*0.245)+sin(180*(1.25-0.245*2)))
        =2/3*14300*0.5/4*0.117431^3+300*6.283*0.44/3.14159*(sin(180*0.245)+sin(180*(1.25-0.245*2)))
        =2/3*14300*0.5/4*0.117431^3+300*6.283*0.44/3.14159*(sin44.1+sin(180*(1.25-0.245*2)))
        =2/3*14300*0.5/4*0.117431^3+300*6.283*0.44/3.14159*(sin44.1+sin(180*0.76))
        =2/3*14300*0.5/4*0.117431^3+300*6.283*0.44/3.14159*(sin44.1+sin136.8)
        =2/3*14300*0.5/4*0.117431^3+300*6.283*0.44/3.14159*(-0.872684)
        =2/3*14300*0.5/4*0.001619378159174+300*6.283*0.44/3.14159*(-0.872684)
        =0.666667*14300*0.5/4*0.001619378159174+300*6.283*0.44/3.14159*(-0.872684)
        =9533.3381*0.5/4*0.001619378159174+300*6.283*0.44/3.14159*(-0.872684)
        =4766.66905/4*0.001619378159174+300*6.283*0.44/3.14159*(-0.872684)
        =1191.667263*0.001619378159174+300*6.283*0.44/3.14159*(-0.872684)
        =1.92976+300*6.283*0.44/3.14159*(-0.872684)
        =1.92976+1884.9*0.44/3.14159*(-0.872684)
        =1.92976+829.356/3.14159*(-0.872684)
        =1.92976+263.992437*(-0.872684)
        =1.92976+(-230.381976)
        =-228.452216
    答案:2/3*14300*0.5/4*(sin(180*0.245))^3+300*6.283*0.44/3.14159*(sin(180*0.245)+sin(180*(1.25-0.245*2)))=-228.452216
