David, It is probably easiest to save your Excel sheet as a text file and then read that into a Maple worksheet on these lines: restart; A := readdata("C:\\Documents and Settings\\David Parker\\Stats\\Data.txt",2); plots[pointplot](A); From there you can manipulate A (which is a listlist) as necessary. Hope this helps, J. Tarr

You asked something very like this question previously and you were given a lot of help. Try looking up those answers. Hope this helps, J. Tarr

There are two mistakes in your worksheet. It should be assume(...) not Assume(...), and D is a reserved name so use a different symbol. Having done those two things, Maple will evaluate the integral, though the result doesn't look very pretty. Hope this helps, J. Tarr

In your worksheet you applied the MapToBasis command to two (Cartesian) Vectors. The result was two (polar) Vectors – not Vector Fields. This is explained in the worksheet of examples for the VectorCalculus package (see ?examples,VectorCalculus). The worksheet linked below shows how two Vector Fields in polar coordinates can be aligned parallel to the Ox and Oy axes. Hope this helps, J.

Walter, Ctrl+L is a keyboard shortcut for Insert>Label. Executing a command with just a label inserted in it re-displays the expression/equation of that label. But you have to have "Show equation labels" enabled in Tools>Options>Display. Hope that solves your problem. J. Tarr

Walter, I'm not sure exactly what you want, but perhaps something like this is will do: restart; `1st expression` = (a^5+b^5)/(a+b); `normalized 1st expression` = normal(rhs(%)); Then to re-display the 1st expression, do Ctrl+L and insert 1 and execute. Hope this helps, J. Tarr

You will find these functions defined in the Maple help pages. Click on the help icon in the upper toolbar or press Ctrl+F1 and enter Ci or erf in the search box that appears. Hope this helps, J. Tarr

Audrey, Sorry it didn't quite work. Here's a step by step guide: a. In worksheet mode create a new execution group and convert it to text using Ctrl+T or Format>Convert To>Plain Text. b. Type the text that you want. c. Press Enter twice. d. Move the cursor to the (beginning of the) blank line immediately following the last line of text. e. Click the "Center Paragraph" icon or Format>Paragraph>Center. This will move the cursor to the center of the line. Paste the copy of your 1st plot. f. Move the cursor to the next line down. It should be over at the left side. g. Repeat b to f ad inf. You could download this and experiment with it. Hope this helps, J. Tarr

Audrey, Glad to hear that it works. You can center plots using Format>Paragraph>Center or using the icon in the lower Toolbar. It's easier to do this before pasting your plot into the worksheet. Good luck with your work, J. Tarr

Try doing this. Open a new worksheet in worksheet mode (File>New>Worksheet Mode or Ctrl+N). Then copy and paste the following into that new worksheet, and finally execute each command in turn. Examine the worksheet and make any changes you want and re-execute. I suggest that you save the worksheet for further use and study. restart; A := Matrix([[1,0],[1,2]]); B := Vector([1,-1]); x := Vector([x1(t),x2(t)]); xprime := map(diff,x,t); eq := xprime = A.x + B; eqn1 := xprime[1]=(A.x+B)[1]; eqn2 := xprime[2]=(A.x+B)[2]; dsols := dsolve({eqn1,eqn2,x1(0)=1,x2(0)=0},{x1(t),x2(t)}); assign(dsols); plot([x1(t),x2(t)],t=-5..3/2); Hope this helps, J. Tarr

The program that you posted contains two errors: There is an extra right bracket at the end of the print command. The final logical statement evaluates (b or not(c)), whereas your task asked for (b and not(c)). You need to check all that you have done very carefully. That should eliminate any errors which may be causing you problems on your Mac. Hope this helps, J. Tarr

Koen, You could do something like this, restart; for n from 1 to 3 do f:=x^n: p||n := plot(f,x): end do: plots[display]([p1,p2,p3]); Hope this helps, J. Tarr

Audrey, After writing some text, create a couple of blank lines (press enter twice). Place the cursor in the upper of the two blank lines and paste in the copy of the plot that you want in the text. Then continue your text in the line after the plot. Here's an example. Hope this helps, J. Tarr View 724_Text and plot.mw on MapleNet or Download 724_Text and plot.mw

Audrey, Have you tried copying your previously plotted graph and then pasting your graph into a blank line in your text? It works for me. Hope this helps, J. Tarr

Maple's spell checker checks text but not Maple input. So try this. Open a new worksheet (File>New>Worksheet Mode), then at the command prompt type "now is the qoittja", then press F7 and you will get "spellcheck complete". Now press "enter" and a new command prompt will appear, then press Ctrl+T (or Format>Convert to>Plain Text). Then type "now is the qoittja" and press F7 and the spellchecker will question "qoittja". Hope this helps, J. Tarr
