3.3 Other Solvers • 57Maple displays a vertical line at the asymptote, unless you specifydiscont=true.> plot(expr, x=-5..5, y=-10..10);1086y42–4 –2–2 0 2 4x–4–6–8–10Maple removes the singularity x = 1 from the expression before solvingit. Independent of the method or tools you use to solve equations,always check your results. These checks are easy to do in Maple.3.3 Other SolversMaple contains a number of specialized solve commands. Since you arenot as likely to find these as useful as the more general commands, solveand fsolve, this section only briefly mentions some of them. If you requiremore details on any of these commands, take advantage of the online helpby entering ? and the command name at the Maple prompt.Finding Integer SolutionsThe isolve command finds integer solutions to equations, solving for allunknowns in the expression(s).> isolve({3*x-4*y=7});{x = 5 + 4 _Z1 , y = 2 + 3 _Z1 }Maple uses the global names _Z1, . . . , _Zn to denote the integer parametersof the solution.
