I am a newbie in Maple.

I am trying to evaluate and to display the electric field with Maple in Document Mode.

I have several questions:

1. How to delete errors from prevous calculations?

2. How to delete formuls from previous calculations?

3. How to wirite vector functions?

4. How to evaluate vector funcitons?

5. How to display 3D plot of a funciton?...

Hi! Normally recursively defined functions work well, but if I use a sum inside, this happens:

> y:=n->sum(y(k),k=0..n-1);

                                   n - 1

I need to send a Maple worksheet (.mw) to someone who is not a Maple user,doesn't have Maple installed.So what is the simplest possible solution now?How can I convert this into a pdf/doc/ps/eps  file so that any document viewer can open it?

Hi,

I'm having some troubles in solving an equation which has the following form:

S. Inv(R). T = L

whereas S is a [nx1] row vector, T is a [1xn] colomn vector, R is a [nxn]Matrix and L is a scalar.

The problem is that R is a quite complicated function of a single variable for which i want to solve this system. Thus the analytical matrix inversion doesnt work.

Do you have any suggestions how i can solve this in a numerical way?...

Hi, Can Maples Logic package solve these problems?

How can they be formulated and solved in Maple? rgds

Let's say that the following arguments are true: Some gatekeepers are warriors. Some warriors are cowards. Therefore, we can conclude that some gatekeepers must be cowards. Is this conclusion true or false? answer: F

 Let's say that the following arguments are true: All Parkers are Franks. All Franks are smart. Therefore, we can conclude...

Hi, I would like to fit my data with a physical model. Unfortunately, I have the model in the form of an ODE which can be solved numerically only. So made a procedure output as follows:

I solve one task. And as a result I receive a matrix and export it to a textfile. Then I receive another matrix and try to export it to the same textfile. Another words I need to add a last matrix to previous one but when I use exportmatrix command the last matrix overwrites previous one. What can do?

Hi, dear mapleprimes. These days I'm preparing my thesis. I use maple to generate some figures, and save them as .jpg. These figures are very clear when I insert them into a word document (my thesis). But after I print the document, the figures looks unclear. It seems that they are cuted from other papers, but actually they are not.

I think it is important to print clear figures, I want the figures can be printed clearly...

Dear guys

I have a set of ODEs but when I solve it maple shows this massage:

"Error, (in dsolve/numeric/SC/firststep) unable to evaluate the partial derivatives of f(x,y) for stiff solution"

If I neglect the option "stiff=true", it works but then when I want to plot something maple says:

"Warning, cannot evaluate the solution past the initial point, problem may be complex, initially singular or improperly set up"

and only shows a coordinate...

Good afternoon

I don´t know if a principal worksheet in maple can call other secundary worksheets.

Please help me. I don´t know the code, or function

Hello experts,

I have function that I need to plot it  in hisogram:

f3 := (n) -> (2*n)!*(lambda)^n/(((n)!^2)*2^(2*n)*(lambda+1)^(n+0.5));

n=0..20 and lambda:=10

thanks.

I find the singularities of an expression by using the function singular and the result of this is what I call t1a below.

I am getting bcak into MAPLE after being away for a while, so this might be a trivial question, but...

I am using plots[pointplot] to plot a series of points.  The default min and max values on the x and y axes of the plot are the corresponding min and max values of the x(first) coordinates and y(second) coordinates of the points.  I can change this by left-clicking on the plot and adjusting the axes properties, but I am wondering if it would be possible...

Hi, folks.

I am presently working on a computer with no math software installed and would like some help with one quartic equation:

227.0207672x^4 - 703.4677734x^3 + 845.7313843x^2 - 465.6021423x + 98.41660309 = 0

I just need numeric results.

I tried to use the online Maple Math Oracles, but they don't seem to be working right now (at least, not for me).

I have done searches for other online tools, but so many come up with different answers.
