I'm not proficient with Maxima, but I was able to do this: wxMaxima (%i1) load(solve_rat_ineq)$ (%i2) solve_rat_ineq(y^2>2); (%o2) [[y<sqrt(2)],[y>sqrt(2)]] (%i3) s: %o2$ (%i4) map(lhs, map(first, s)); (%o4) [y,y] (%i5) map(rhs, map(first, s)); (%o5) [sqrt(2),sqrt(2)] Please note: lhs() returned the left side of the inequality, and rhs() returned the right hand side of the inequality, unambiguously. "Maybe someday the developer's will find time ..." The hp prime is very useful, and seems to be evolving. I do hope it continues.
