Thanks but plot won't work here either. Already tried it as well. The really messed up part is that I have worksheets that have commands that look almost identical to these and they work. I just don't see what I'm missing in this one... glenn

I just figured it out. This is yet another thing that I just don't understand in Maple. I copied and pasted the restart and with(plot): lines from another worksheet into this document. But unless you physically click on each line and hit the enter key they don't work. Is there a way to get Maple to work without physically having to click on every line in the worksheet to have them execute? Thanks, glenn

Thanks, I think I'll switch back to the document view instead of worksheet as its a little more obvious what you're typing. I wish Maple had an easier method for entering equations in Document view as its rather cumbersome compared to Mathcad. I especially like the spacebar allowing you to quickly select regions while you type instead of having to use the arrow keys to move around while you're trying to type an equation out. Does anyone know if there is a way to make Maple work a little more like that? Thanks, glenn

Well, I just went back and copied the functions up a little higher in the page and it works so must be something else in the sheet causing the problem. Sorry for the trouble... glenn

well, one thing I did that does work but only for 2 functions that end up closing themselves is to add both into the function. ie: VolumeOfRevolution( sqrt(x),x,x=0..1, axis=vertical, distancefromaxis=0, output=plot); This will actually create a closed solid but only because the two functions are closed themselves. In my example, I have 1 curve and then two straight vertical lines that would make it closed with the X-axis. I don't know how to get it to accept all 3 of these curves though... Thanks, glenn

Example: VolumeOfRevolution(1/x, x = 1 .. 2,axis= 'horizontal', 'distancefromaxis' = 0, 'output' = 'plot') Can anyone tell me how to graph this in Maple. Its a 1/x curve with two verticle pieces at 1 and 2 that connect the curve to the X axis. I want to then rotate around the x-axis which should end up with a complete solid and no holes. thanks, glenn

Thanks, glenn

Thanks, glenn

Actually there is a cure as I just figured it out. You have to set numpoints= to higher number of points to enable it to smooth the curve out, but thanks... glenn

Thanks guys, going to start reading chapter 5 now... glenn

Nevermind to the keystroke things. I see now that it uses words instead of single keystrokes for things. Just noticed that the hints are telling me how to type it... :-) So the only things I need are the working with graph info. How to set view and how to quickly zoom in on an area as well as plotting multiple functions in the same graph view... Thanks, glenn
