The Ryacas package might be able to do it...

Emne: [R] How can R be used to solve algebra equations?




suppose I have this equation:
(x^2+y^2+3z^3)/(5*z^2*x^3)=0

and I want to find x in relation to the other variables which actually is:

x=sqrt(-3*z^3-y^2) or x=-sqrt(-3*z^3-y^2)

Can R give me this expression solution? I know there is uniroot, but here I
want the "expression" not the value, because I do  not have values for y and
z.

Thanks
