I'm currently using Maple to plot a 2-D (x,y) function F(I) that, at each point, is a function of a nasty integral, I(x,y,t)dt between -infinity and some constant. Maple does a good job of plotting the data and the resulting plot looks fine. The trouble is that when I ask Maple to just evaluate F for a single (x,y) rather than over the full range of (x,y) it tells me that it is not analytically tractable and it cannot produce a result.

If this is true, then how on EARTH is it plotting them in the first place? Where have these values in the plot come from and why do they look so reasonable? What is Maple doing that lets it plot a dataset it is incapable of producing?

Thanks
