〖1/1算式〗
    作业：求算式 2*500/sqrt(3)*(1+ln(0.0749/0.05))-360-360*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0749^2)+1) 的值.
    题型：数学计算
    解:
          2*500/sqrt(3)*(1+ln(0.0749/0.05))-360-360*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0749^2)+1)
        =2*500/sqrt3*(1+ln(0.0749/0.05))-360-360*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0749^2)+1)
        =2*500/sqrt3*(1+ln1.498)-360-360*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0749^2)+1)
        =2*500/sqrt3*1.404131-360-360*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0749^2)+1)
        =2*500/sqrt3*1.404131-360-360*0.05^2/0.0075*((0.1^2/0.0749^2)+1)
        =2*500/sqrt3*1.404131-360-360*0.05^2/0.0075*(1.782528+1)
        =2*500/sqrt3*1.404131-360-360*0.05^2/0.0075*2.782528
        =2*500/1.732051*1.404131-360-360*0.05^2/0.0075*2.782528
        =2*500/1.732051*1.404131-360-360*0.0025/0.0075*2.782528
        =1000/1.732051*1.404131-360-360*0.0025/0.0075*2.782528
        =577.350205*1.404131-360-360*0.0025/0.0075*2.782528
        =810.675321-360-360*0.0025/0.0075*2.782528
        =810.675321-360-0.9/0.0075*2.782528
        =810.675321-360-120*2.782528
        =810.675321-360-333.90336
        =450.675321-333.90336
        =116.771961
    答案:2*500/sqrt(3)*(1+ln(0.0749/0.05))-360-360*0.05^2/(0.1^2-0.05^2)*((0.1^2/0.0749^2)+1)=116.771961
