  • 方程不是有结果吗!输入T1回车,就出来了

    T1=

    -2/5*L1*(-225*y+25*BX3*3^(1/2)*z-25*x*3^(1/2)*BZ3+25*3^(1/2)*x*BZ2-25*3^(1/2)*BX2*z+245*3^(1/2)*BX3-245*3^(1/2)*BX2-125*3^(1/2)*z-45*x*BY3+45*BX3*y-1225*3^(1/2)-735*BY2-735*BY3+294*BY2*BX3-294*BY3*BX2-45*y*BX2+45*BY2*x-75*BY2*z+75*y*BZ2-75*z*BY3+75*BZ3*y-30*z*BY3*BX2+30*BZ3*y*BX2+30*x*BY3*BZ2-30*BX3*y*BZ2+30*z*BY2*BX3-30*BZ3*BY2*x)/(-30*BY2*BZ1-50*3^(1/2)*BZ1-50*3^(1/2)*BZ2+20*3^(1/2)*BX3*BZ2-20*3^(1/2)*BX2*BZ3-10*3^(1/2)*BX2*BZ1-10*3^(1/2)*BZ3*BX1+10*3^(1/2)*BZ2*BX1+10*3^(1/2)*BZ1*BX3-45*3^(1/2)*BX3+45*3^(1/2)*BX2-50*3^(1/2)*BZ3+225*3^(1/2)-90*BY1+45*BY2+45*BY3-18*BY1*BX2+18*BY2*BX1+18*BY1*BX3-18*BY3*BX1-18*BY2*BX3+30*BY1*BZ3+30*BY1*BZ2+18*BY3*BX2-30*BY3*BZ1+12*BY3*BX1*BZ2+12*BY2*BZ1*BX3-12*BY1*BX3*BZ2-12*BY3*BZ1*BX2-12*BY2*BX1*BZ3+12*BY1*BX2*BZ3)
