y =
0.70710678118654752440084436210485*(10.0 - 3.0*y^2)^(1/2)
-0.70710678118654752440084436210485*(10.0 - 3.0*y^2)^(1/2)
谁帮我下面函数啊，解不了
[x0 y0 x1 y1 x2 y2]=solve('y1*a^2*(x1-x0)=x1*b^2*(y1-y0)','y2*c^2*(x2-x0)=x2*d^2*(y2-y0)','(y1-y0)^2+(x1-x0)^2=r^2','(y2-y0)^2+(x2-x0)^2=r^2','x1^2*b^2+y1^2*a^2=a^2*b^2','x2^2*d^2+y2^2*c^2=c^2*d^2','x0','y0','x1','y1','x2','y2')

你求的是符号解。并且，这道题的答案有两个解
