Trying to solve a system of equations with radicals, i get an error message:
`algsys' cannot solve - system too complicated.
-- an error. Quitting. To debug this try debugmode(true);
Even trying to solve a very simple radical equation, i get a wrong answer:
(%o3) [x = sqrt(x + 1) - 9]
IS there a way to handle radical equations? maybe some external package?
Anyways, regardless of external packages, i consider that the solve command
shoud handle these kind of equations, since the method of sqaring both sides
of the equality is not what i would call sophisticated. I am trying to
introduce maxima in my high school classes, and my students would laugh if
they find that they know how to solve these systems better than the computer.
