Hello
I am quite new to sage and I am trying to copy a graph created using
mathcad. The following code seems to do the result but i am not sure if it
is the best way of doing it. Any help would be appreciated
var('a','b')
Slopefield = plot_slope_field((a+b), (a,-5,5), (b,-5,5))
x = var('x')
y = function('y', x)
DE = diff(y,x) - x-y
f = desolve(DE, [y,x], (0,0))
SolnPlot = plot(f, (x, -5,5))
(SolnPlot+Slopefield).show(aspect_ratio=1, xmin=-5, xmax=5, ymin=-5, ymax=5)
Thanks Dan
ps the above code has been cut and pasted from a sage doc and slightly
modified by myself and i have no idea why the -x-y works in the DE part.
