MaplePrimes Questions

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:

solL:=dsolve({Lpde,ICS}, numeric, method=rkf45, output=listprocedure, parameters=[lambda[0],T[m]]);

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.



Dear All

I have an equation that is related to some other equations. The main equation and some of the others are in the sum format. I want to solve the main equation in parametric format.

main equation: i want to solve it for m based on other parameters (n,p,alpha,c and perhaps k)

sum(m/(k*p*c+m*i^alpha), i = 1 .. n)-m = 0

there are some other requirements:

1/k = sum(1/i^alpha, i = 1 .. n)

sum(k/i^alpha, i = 1 .. n) = 1
