The exact solution shows periodic behavior, with a fixed period and amplitude. Graphics saved as "b1g3_predator_prey.png" stiff_b1g3() Use b1g3() to solve the stiff ODE. Graphics saved as "b1g3_stiff.png" humps_b1g3(): Solve the humps ODE using b1g3(). Graphics saved as "b1g3_humps.png" b1g3_test(): Normal end of execution. Tue Nov 18 20:04:50 2025
