I have a vector containing a variable
>vec1[1];
var1
I have another vector containing a symbolic solution.
>vec2[1];
a + b + c
I wish to assign a + b +c to var1 so that
>var1;
a + b_+ c
How do I do that? All of my usual methods seem to come unstuck.

Hello,
I'm working on a document and I decided to print it out to do some editing. I have enabled page numbers, and when I do a print preview I see the page numbers at the bottom of the all of the pages. But when I print out the file, the page number appears at the bottom of the first page but not on any of the next pages. This happens both when I print it to our office printer and when I print it to a PDF file.
Any suggestions?

1)
How do I view the source code of, say,
```
(Student[Calculus1][AntiderivativeTutor])();
```

2)
I'm using a Maplet where a student will enter an expression into a MathMLEditor.
I then want to compare this expression to one that the computer has already generated, to see if they can identify the inside function in a composite function, for instance.
Once they enter their expression into the Editor, I use a Get command to extract it, and MathML[Import] to turn it into Maple expression to compare it with the computer-generated one. This works fine with functions like 1/x^9 (which you can type in easily into the editor), but really causes problems with ln(x) or sin(x). If you type in "sin(x)" into the Editor, MathML[Import] will interpret that as

Hello All
Dear Maplesoft professionals,
I have a classic internal Maple procedure. It works by call in Maple session like this
MyProc[Function]([3/5,7,4.25],
["blue","red","gold"]);
I am planning to call it from OpenMaple application (fast and correct and many times).
The members of lists will change many times at .exe session (user dialog).
What the best way to call it from C code
1. Function Conection
DagProc = EvalMapleStatement(kv, "MyProc[Function];");
2. ???? What kind manipulation by data
[3/5,7,4.25],
["blue","red","gold"]

I just uploaded the file Georgeworksheet18.mw. I am looking for a result such that when I collapse the document block I see the statement
The answer to 4+3 is 7.
on one line. I would like it so that if I expand the document block, and change the command line to
4 + 4
and then collapse the document block I will see
The answer to 4 + 4 is 8.
Is there any way to accomplish this?

Dear Maple users,
I am trying to use Minimax to create a rational approximation to a function over a specified approximation interval. But, I keep getting the following error message. Can someone help?
> with(numapprox):
> Digits:=50;
Digits := 50
> minimax(tanh(sqrt(x))/sqrt(x), x=1..10^4, [13,14]);
Error, (in numapprox/remez) error curve fails to oscillate sufficiently; try different degrees
Thanks,
Adnan.

Hi;
Is there any way to find a closed form of the following integral by maple, where theta is a real constant.
cheers
Sayed
int(x*exp(-I*x*theta)/sinh(1/2*Pi*x),x=-infinity..infinity);

The problem i have is this, the plot that i am suppose to recieve is one that looks like the 'pointplot3d' below, yet i recieve something which doesn't. Any suggestions as to how to circumvent this?
with(plots):Digits:=15:
> Omega[0,1]:=.825352549049169:
plot3d(MathieuCE(0,Omega[0,1],r*I)*MathieuCE(0,Omega[0,1],theta),theta=0..2*Pi,r=0..1,coords=ellcylindrical,axes=FRAMED);
points1:={seq(seq([T/100,2*Pi*S/100,MathieuCE(0,Omega[0,1],2*Pi*S/100)*MathieuCE(0,Omega[0,1],I*T/100)],T=1..100), S=1..100)}:
pointplot3d(points1,coords=ellcylindrical, axes=FRAMED, color=red, style=wireframe);

in document mode I like to add a descriptive text after the inline output to label what answer is. You cant just switch to text mode and start typing, it does not work. The only way I have been able to do this is to use the next float or next prime command then backspace twice to erase that output and then I can switch to text mode and append text.
Is there a easier way to do this?

How do I display / calculate -1.60x10^-19 when calculating Coulombs?
This returns a "Error, invalid power" in Maple 10 (student) and Classic Maple (student) and in the calculator (student).!
Frustrating, Yes I am a student and a new user and I need the help the software promises to provide.

I'm trying to solve a system of equations in maple and I have no idea why it's doing what it's doing but it certainly isn't working. Anybody have an idea what's going on?

A colleague asked me about this, and I couldn't help him:
```
> g:=y+exp(2*t):
> y2:=subs([y=3,t=0.1],g);
y2 := 4.221402758
> subs([y=y2,t=0.1],g);
4.221402758
```

Why has not the new value of y2 been substituted for y in this last expression? And the same thing happens for eval.
Thanks,
Alasdair

I've already found the commando's logplot and loglogplot on my own. The first defines a log scale for the y axe. The second defines a log scale for both the axes.
Now is my question where could I find the command for plotting a log scale for the x axe.
I suspect it is something special because I could not find it in the library plots.
My excuses for my terrible English!

I am trying to write a paper in which I can, for presentation purposes, collapse document blocks and have the code not shown. I am running into the problem that when I collapse some document blocks code within is not displayed but when I collpase other document blocks all that goes away is the red prompt. I can't figure out why the difference. The attached file has two document blocks which, as far as I can tell, are identical except for a few words of text. When I collpase the first block the code remains displayed, but when I collapse the second block it does not. Can anyone figure out why the difference?
