I'm just learning ODEs and have a textbook problem I'm trying to plot in Maple 13. For the ODEs, In the first year I have a certain behaviour (contaminated water flows into a pool) and in subsequent years fresh water enters the pool. I'd like to show both behaviours on the same plot. How would you do this? Here is what I did to make two separate plots: In the first year - I have contaminatation of a pool: ode1 := diff(q(t), t) = 3-3*q(t)/10^4 DEplot(ode1, q(t), t = 0 .. 8760, [q(0) = 0], title = "contaminant accumulation in the first year") In second years and subsequent years, the contamination stops and is replaced by fresh water: ode2 := diff(q(t), t) = -3*q(t)/10^4; DEplot(ode2, q(t), t = 0 .. 17520, [q(0) = 17520], title = "contaminant dissipation in second year"); Thanks, Sean
