Actually there is no need to change the variable it does work with x on 16.02.  You just need to adjust the x range to -4..2

So it appears you can't just arbitrarily pick a range (which should work) but you must have a range of x that is suitable.  The x range is dependent on the y range chosen and vice versa.

DEplot(diff(y(x), x) = x+y(x), y(x), x = -4 .. 2, y(x) = -5 .. 5, [[0, 0]], linecolor = black)

However using the x range -5..5 will not produce the solution curve unless you increase your y range to something like y=-5..130

Changing the the function y to y(t) instead works

Also note if your y range is not large enough for the solution it will not display so either remove the y range or choose a suitable larger range that will allow the solution to be visible.  If you want the smaller y range the x sorry t range will have to be smaller. 

So changing to this will help

A:=DEplot(y'(t)=t+y(t),y(t),t=-5..5,[[0,0]],linecolor=black);

display(A)

Very enlightening.  Thank you for that link!

I would also like to add this interview with Richard Feynman - The pleasure of finding things out

Well the issue was there since primes 2, but not everyone announces they see all the trees in the forest.

An application of this would be to find solutions for the game Boggle.

Time travel is alive and well here on mapleprimes.  We can answer questions before they are even asked.

He is the first person I have seen to actually have filled out the document properties section.

That book came packaged with the very first Maple version I purchased Maple Vr3.  Great to see Maplesoft's pro-active environmental move.  I could tie in one point here, and that is if versions were released once every 2 years that would have also cut down on new printed manuals.

Personally I like printed manuals, seeing now that those versions will be discontinued will there be discounted prices on older printed manual versions? 

Thanks for the answers, much appreciated.

I suppose that could do. Not to bring our options to an end.

Regarding pulling the data out of the graph for a generalization, I suppose you would mean using indets and op, so something like this if

a:= Statistics:-BubblePlot([4, 5, 2, 3], [1, 2, 7, 8], [8, 1, 3, 2],view=[default,0..9]):

myrange:=op(indets(a, specfunc(anything, VIEW)))

myx:=op(myrange)[1]
myy:=op(myrange)[2]
