Try putting quotation marks around "Node", "Saddle", "Center" and "Spiral". It looks like Maple is trying to evaluate a string that you just want to have printed out. In general you should always put quotation marks when entering Strings in Maple. ____ William Spaetzel Marketing Engineer, Maplesoft

In case someone reading this is wondering how to find the files they are here: Worksheet View 2292_GeorgeWorksheet1.mw on MapleNet or Download 2292_GeorgeWorksheet1.mw Image My suggestion would be to save your Turbocad file as a .jpg and then open it in an image editor and resize it to the size that you want. Then save that file and insert it into Maple. You'll find than an actuall image editor will do a better job of resizing images than Maple can. If you don't have an image editor, you can use MaplePrimes to resize your images, go to this url: http://www.mapleprimes.com/scripts/image.php?image=http://www.mapleprimes.com/files/2292_F1.jpg&width=300&height=300 If you look at the URL you'll see width=300 and height=300 you can change these numbers to any size that you want and you'll get an image with the given maximum width and height. ____ William Spaetzel Marketing Engineer, Maplesoft

I just wrote a worksheet that should demonstrate exactly what you are looking for. Please check it out and let me know what you think of it. View 1_delayPlot.mw on MapleNet or Download 1_delayPlot.mw ____ William Spaetzel Marketing Engineer, Maplesoft

You can use plots[display] to combine plots:

> points := [[1,2],[4,3], [5,2], [2, 3] ]:
points2 := [[4,1], [6,3],[3,5], [3,3] ]:

> with(plots):

> a:=pointplot(points,color=red):

> b:=pointplot(points2,color = blue):

> plots[display]([a,b]);

And here I am again, you can plot these functions in the same way as I did for your previous post, except this time with a 3-D plot

Create the functions:

And plot the functions. You can change the ranges to anything you want.

Could you please post the code that you have created as a reply? It would make it easier to troubleshoot your exact problem. It should be simple to plot the output of a procedure. ____ William Spaetzel Marketing Engineer, Maplesoft

Maple does have if and else as you ask for, it does not link directly to execution groups, but it is easy to produce the effect that you want using if and else.

Define the variable that the if is reliant on:

> x:=7;

Now create the if:

> if( x > 5 ) then
print ("x is bigger than 5");
else
print ("x is less than or equal to 5");
end if;

Try changing the value of x, and you'll get a different response

If you call interface(rtablesize=n), Maple will display Matrices up to dimension n inline. > interface(rtablesize=20); I am using a smaller matrix here so that it will fit well on MaplePrimes, but you can change this to have it work with larger Matrices as well > M:=LinearAlgebra:-RandomMatrix(8,8); Read more about it in this help page: > ?Matrix This post generated using the online HTML conversion tool Download the original worksheet View worksheet on MapleNET

I hope that this will answer your questions, Enter your function like this: So you can find a value by entering Plot the function using the plot command Find the derivative, its value gives us the slope at a point And now plot that To find the the maximum value, we will use the optimization package And then use the Maximize command, giving it a range of valid values for This post generated using the MaplePrimes File Manager Download the original worksheet | View worksheet on MapleNet
