How can I add blank spaces after each comma in the following
so that the output will be easier to read?
print(X_bar[1] = Mean_SampleMeans1, S[1]^2 = Var_SampleMeans1, S[1] = SD_SampleMeans1);
X_bar[1] = 5.993500000, S[1]^2 = 5.102310060, S[1] = 2.258829356
I am using Maple 10 worksheet mode (Mac). Maple ignores any
additional spaces after commas in the input.
Thanks for your help.

Nowadays i am trying to program a kind of computer algorithm to generate a random mathematical formula, and I'm having an argument with another mapleTA programer, the question is this one:
What is more efficient, have a question for all the types of formulas with random variables or have **only** one question with a code like:
```
$a = range(-5,5);
$ea= range(1,5);
$eb= range(1,5);
$ec= range(1,5);
$eq1 = switch(rint(7),maple('$a*x^$ea*y^$eb*z^$ec'),maple('$a*x^$ea*y^$eb'),maple('$a*x^$ea*z^$ec'),maple('$a*y^$eb*z^$ec'),maple('$a*x^$ea'),maple('$a*y^$eb'),maple('$a*z^$ec'));
```

I'm trying to insert a random polynom in a mathml question, let me explain:
code:
$a = range(-5,5)
$b = range(-5,5)
$c = range(-5,5)
$eq = maple('MathML:-ExportPresentation(($a)*x+($b)*y+($c)*z = 0))
question:

Hello,
is there a way to give new properties to built-in operators, such as `+` or `*`?
For example, I have my own type MYTYPE and procedure for adding MyAdd(a::MYTYPE, b::MYTYPE). Now, I would like to use: a + b instead of MyAdd(a,b). Is it possible?
Thank you.

I seem to be having some trouble with scalar multiplication. Perhaps you all can help out.
Here is what I have;
with(LinearAlgebra):
A:= matrix(3,3,[1,2,3,4,5,6,7,8,9]);
ScalarMultiply(A,3);
I was hoping that would work, but after the ScalarMultiply command I get
"Error, (in LinearAlgebra:-ScalarMultiply) expects its 1st argument, MV, to be of type {Matrix,Vector}, but received A"
Any ideas where I am going wrong?
Thanks in advance.

Probably me doing something wrong but just wanted to know....
I wanted to assign a value to a variable... delta x
but I wanted to use the greek delta with the x. (e.g. Δx)
Maple doen't like it, and flags the error.
Error, first argument to _Inert_ASSIGN must be assignable
I know it is only cosmetic but I just wanted know if its possible.
Thanks,

How do I find the numeric value of these equation.I want actual value of all symbols( alpha,beta and gamma)
1) b_2 = -3.464909430*RootOf(-gamma^2+alpha*beta+(-gamma^2-4*alpha*beta)*_Z+(gamma^2+4*alpha*beta)*_Z^2, label = _L1)+1.732454715
2) b_1 = RootOf(-gamma^2+alpha*beta+(-gamma^2-4*alpha*beta)*_Z+(gamma^2+4*alpha*beta)*_Z^2, label = _L1)/alpha
3) Z = -.5772156649*alpha/(2.*RootOf(-gamma^2+alpha*beta+(-gamma^2-4*alpha*beta)*_Z+(gamma^2+4*alpha*beta)*_Z^2, label = _L1)-1.)

Please help me find the numeric values of a_1,a_2,b_1 and b_2, base on the below equation.
solve({a_1^2*alpha+a_2^2*beta=a_1,2*a_1*a_2*alpha+a_2^2*gamma=a_2,a_1*b_1*alpha+a_2*b_2*beta=b_1,a_1*b_2*alpha+a_2*b_1*alpha+a_2*b_2*gamma=b_2,b_1^2*alpha+b_2^2*beta=a_1+b_1,2*b_1*b_2*alpha+b_2^2*gamma=a_2+b_2,a_1*b_2<>b_1*a_2},[a_1,a_2,b_1,b_2]);

I'm new to Maple and just starting a ODE class. I attempted to do a Directional Field plot using DEplot. The plot displayed only Q3 and no mater what I tried would not plot the other quadrants.
My inputs:
with(DEtools):
desgn := diff(y(x),x)=-x/y
DEplot(desgn,y(x),x=-10…10,y=-10…10);
Seems simple enough is there something I’m missing? I tried to change the range by the right click over the plot; did nothing.
Sorry if this is overly simple but, I’m still learning… Thanks for any help anyone can offer.

I am teaching a course on wavelets. I have two items that are giving me trouble with using Maple 10.
1. I read a JPEG image into my worksheet, and then I want to multiply it by a filter matrix. I get an error because the filter is a Matrix and the image is an Array. How do I fix this problem?
2. Once I have changed the image, I want to see the result. The only way I have found to do it is to save the resulting array to the hard drive, and then use the Insert tab, and choose image. There has to be a way to do this without having to store the Array. How?

I had trouble with Maple in my calculus II class when working an improper integral. See the uploaded worksheet at

How to get the set of non-neg-int solution of x+y+z=n?

I have matrix C:
C:= matrix([[a,b,c],[d,e,f],[g,h,i]])=7;
and want to find the determinant of matrix K.
K:=matrix([[a+d,b+e,c+f],[d,e,f],[g,h,i]]);
How do I do this? Im not very familiar with the linalg-package in Maple so I need help.

I am exporting a 3D colored ps figure by using the output command:
plotsetup(ps,plotoutput=`plot.ps`,plotoptions=`portrait,noborder,color=RGB`);
Without changing the grid size, the figure, in the postcript file, appears with less accuracy than the one that would appear in the Maple environment.
Is there an option to be defined that improves the picture resolution without the need of increasing the number of points of the grid?

In the student part of maple 10, it says:
" More than just the answer
Maple 10, in addition to providing the answer, also displays all the required steps and the “thinking” behind the math problems you are facing."
But I can't see anywhere in the program where this is available. Put something in and all it does is give you a final answer:
One simple example:
solve(y^2 = (x(x+1))/2);
just gets you the final answer
