Thank-you djc for answering my first question here as well. I hope that in time I'll have Maple language down as well as I know so many who have come before me have it. For now, please forgive these elementary questions. I am new to Maple and a beginning Math major, but I hope as time progresses (and I complete more classes) I will have some more complex questions to pose here, which I hope might be of use to others. Perhaps there are other beginning students who have the same questions I do and, if so, I hope my posing them here will help them. So, here goes: I'm working on a simple precalculus equation, the graph of the equation y = x^3-2*sqrt(x). I'm plugging in certain coordinates to find if they satisfy the equation and are on the graph. I solved (x,y) for (1,-1) and the equation holds true, but when I use the graphing software to right-click on the equation to get a graph using Plot Builder (2-D Implicit Plot), it shows a curve of points only in quadrant I; however, when I use Evaluate and plug in (1,-1) the equation holds true. Why is (1,-1) not being expressed on the graph, in quadrant IV? TIA, Olivier

It worked exactly as you stated. Thank-you indeed - and also for the additional help. Now I know exactly where to come with questions re Maple coding. What a terrific thread. - Olivier

How do I plot a triangle with three points A, B, C and then additionally have text inserted at each point corresponding to those points so that they are marked A, B and C? How do I enter text anywhere else?
