[Maxima] Inequalities

[Barton Willis]

For inequalities involving rational expressions, you can try:

 (%i6) load("solve_rat_ineq.mac")$

 (%i7) solve_rat_ineq((x+5)*(x-9) >= 0);
 (%o7) [[x<=-5],[x>=9]]

 (%i8) solve_rat_ineq((x+5) /(x-9) >= 4);
 (%o8) [[x>9,x<=41/3]]

 (%i10) solve_rat_ineq((x+5)*(x-13)/(x-9) >= 4);
 (%o10) [[x>=6-sqrt(65),x<9],[x>=sqrt(65)+6]]
