Hello,

I just bought a new PC with Windows 7 Professional 64bit and wanted to install my old Maple 12. I have a notebook with Windows 7 Home Premium 64bit where it runs without any problems. However, Maple 12 does not start whether I put it on compatibility mode or not. There are just two error messages showing up:

Maybe someone can help?

I have a question about the accuracy of Maple functions subs and evalf. I have some expressions such as the following: (more complicated). Let's call it f(n).  f(n) is not a polynomial in n or a rational function. It is a function of n involving exponents and four operations. When I plug in a large n in such an expression, would the answer I get (using evalf with some custom accuracy) be exact?  I am trying to prove f(n)/n >= constant....

Maple experts, please help...

I am facing hard time with ODE functions...:(
I would like to know if there is any command or algorith that could actually clear the solution of "dsolve" command,what I mean... let's say I have ODE function of one indeterminate "y(t)" and its general solution is obtained from dsolve command by setting certain initial conditions. Now, I need to remove that general solution from the system memory so as on next call of ODE function the "y(t...

Hi, can anyone help me with this questions? Thanks!

Use maple to find the general solution to the following system of linear equations:

2x₁  + x₂ - x₃ +3x₄ = 2

x₁ + 2x₂ -x₄ = -1

3x₁ +2x₂ -2x₃ +x₄ = 1

hi all

i am trying to write some code to display:

a) hexagon tiling, rather like a honeycomb in 2D

b)  equilateral triangles tiling , all space filled by said triangles. eg a series of triangles whose base is parallel to base of plot, with inverted triangles filling in the remaining spaces

c) square tiling

for a,b c I  want about 50 of each displayed (all of edge length 1) on the one plot

d)  some code...

My overall goal is to get a high resolution image onto a poster I am creating. I simply have an x and y coordinates for 4095 entries. Excel and maple can obviously do this, but I need to put the end result into PowerPoint. Since I think the Maple graphs look more professional, I was trying to use the Maple Add-In in Excel to simply make a scatter plot. I am assuming the image format between excel and PowerPoint will be much more compatible than that of maple to PowerPoint....

i have a D.E. systems:

J_n=2A_n

S_n+1=J_n

A_n+1=S_n+0.5A_n

and initial conditions A₀=10, J₀=30, S₀=5

can i use rsolve to solve this or is there another ways to solve this systems

One of my friends would like to buy a book about solving multiple integrals and/or ordinary differential equations with Maple (some newer version, let's say 13 and newer).

I know about this site: http://www.maplesoft.com/books/, but can anyone recommend some book(s) which is (are) worth buying?

I NEED YOUR HELP !!!

My computer is a DELL 755 optiplex with an intel video card : Integrated Intel® Graphics Media Accelerator 3100 The operating system is a  redhat Linux.

When I do this in xmaple 13 sofware :

plot(cos(x/2) + sin(2*x), x = 0..4*Pi);

all the windows shut down and I have this error :

X-Error GLXBadDrawable [resid=420029C opcode=(152,11)]

What are the equivalents of eval and evalf for Matricies. In particular how would you display a Matrix which appears in symbolic form to appear with numeric entries.

Hi, I try to integrate the following but it is giving me more than i want, how do I fix that ?

The answer should be just [0.1745329,0.6981317,0.1745329]. The answer with power of minus 9 and minus 10 is insignificant.

Please help. Many thanks

 Hi, 

If I have a function defined as 

                                             F[i]:=x[i]^2 +x[i]*y[i]+y[i]^2    where  x[i]:= (i-1)0.1  and y[i]:=(i-1)0.2 ,    i=1..100

I have the following problem. Two formulas in three variables represent the costs of algorithms. I want a visual of their ratio, so that I can "see" how their relative performance varies. Here is a simple example. I can analyze this example analytically, but you can't always do that.

R := sum(binomial(n+i*d,n),i=1..k-1);
S := binomial(n+k*d,n);
f := unapply(R/S, n, d, k);
A := Array(1..10,1..10,1..10,f,datatype=float[8]);

I want a 3-dimensional rendering...

hi

I am a mechanical engineer student and i am trying to learn mapleSim, but i am having some dificulties.
I am first trying to model an heat exchanger from a domestic water heater. I have found on maples website a costum component and i am trying to do a similar one to start.
The component that i am talking about is this one:

The problem is that after i put my own equations, parameters,...

Hi, I tried to export my answers into an excel file, but my numbers are all complex numbers.

It says "cannot export an rtable with complex values". How can I go about it?

Please advice. Many thanks.
