求解很复杂的二元方程组使用数学软件MATLAB MATHETHMATIA 100
y=(a*(b1*c2-c1*b2)+b*(c1*a2-a1*c2)+a1*b2-b1*a2)/(b1^2*c2^2-2*b1*c2*c1*b2+c1^2*b2^2+c1...
y =
(a*(b1*c2-c1*b2)+b*(c1*a2-a1*c2)+a1*b2-b1*a2)/(b1^2*c2^2-2*b1*c2*c1*b2+c1^2*b2^2+c1^2*a2^2-2*c1*a2*a1*c2+a1^2*c2^2+a1^2*b2^2-2*a1*b2*b1*a2+b1^2*a2^2)^(1/2)-(a*h*b3-a*h*b4+a3*b4+b*h*a4-b*h*a3-b3*a4)/((h+2*(d+c)/(b^2-1+a^2))^2*(b4-b3)^2+(h+2*(d+c)/(b^2-1+a^2))^2*(a4-a3)^2+((a3+2*(d+c)/(b^2-1+a^2)*a)*(b4-b3)-(b3+2*(d+c)/(b^2-1+a^2)*b)*(a4-a3))^2)^(1/2)
z =
-(c1*a2-a1*c2-(a1*b2-b1*a2)*b)*(h+2*(d+c)/(b^2-1+a^2))*(b4-b3)+((a1*b2-b1*a2)*a-b1*c2+c1*b2)*(h+2*(d+c)/(b^2-1+a^2))*(a4-a3)+((b1*c2-c1*b2)*b-(c1*a2-a1*c2)*a)*((a3+2*(d+c)/(b^2-1+a^2)*a)*(b4-b3)-(b3+2*(d+c)/(b^2-1+a^2)*b)*(a4-a3))
求出a b的表达式
matlab解不出来啊
有会mathematica的没有啊,他的符号计算很强大 展开
