Hello all, sorry to bother again. I have the following output in maxima.
input:
solve([log(y^2+x^2)+2*x^2/(y^2+x^2)=0,2*x*y/(y^2+x^2)],[x,y])
result:
[[x=0,y=0]]
I think that the answer is wrong, since the equations are undefined at [0,0].
what happened? (multiplication of both equations by (x^2+y^2) ??)
Is it possible to suppress the answers which do not belong to the
domain of the system?
(I could take the answers and substitute into the original system. But
is there another better way?)
Thank you
Robert Marik
