Question: How do I sum two DEplot graphs to create one graph?

Hi- I'm having trouble figuring out how to combine two separate DEplot graphs into one graph that represents the SUM of the two.  Not two separate DEPlot graphs in one figure, but the sum of two DEplot graphs in one figure.  I'm using Maple 14- anyone know how to do this?  It's probably simple, and I'm just missing it.  Thanks in advance.
