Hi,

I've been using Maple 13 installed on Ubuntu 10.10, but noticed some issues with 3d plots, Maple does not allow me to rotate and drag around 3d plots as it does on my windows 7 boot on the same machine, instead it struggles to even do the 3d plot in the first place and then usually crashes on trying to rotate it.

Also I occassionally get empty GUI boxes when I go to save as etc, instead of any content just a gray pop up box.

Anyone...

Friends,

I am very beginner of Maple softs, in order to proceed with my project i need to model a simple Human Knee joint and  to do its simulation, Somebody please help on this, otherwise i cant able to proceed with my project.

Waiting for a solution

Hi!

Exuse me, can somebody help me???

Maple kills my very important work. I work with Maple 13 and wrote big scientific programm.

I restart my computer, when i try to open file, which works normal yesterday, i saw something like this:

//   How do yo want to open this text file? //

Maple text     Plain text    Maple input   Cancel

Everything i try - no result,...

I'm running a for loop to find a numerical solution to a linear system of equations.

x1:=1

x2:=2

x3:=3

for i from 0 to 10 by 1 do

y1:= f(x2,x3);     <-------------- these are functions of variables solved using the initial approximations above.

y2:= f(x1,x3);

y3:= f(x1,x2);

x1:=y1;    <-------------- Reassignment statements

x2:=y2;

x3:=y3;

end do;

Hello,

I want to solve the differential equation and put the solution in a list to be able to animate the pendulum.

tipe6 := proc (longueur, thetaInitial, rayonBoule, nombrePoints)

local eq, sol, valeurstheta, x, y, plotseq;

eq := ((1/2)*longueur^2+(1/5)*rayonBoule^2)*(diff(theta(t), t))^2+g*l*(cos(theta(t))-cos(thetaInitial)) = 0;

sol := dsolve({theta(0) = thetaInitial, (D(theta))(0) = 0, eq}, theta(t), numeric);

Hi!

I i have a 2nd order ODE where i want to chance the derivatives of x(t) and y(t) exactly at sqrt(x(t)^2+y(t)^2)=1 ,or before, as close to 1 as possible.

I found "event=" in/dsolve/numeric/events, where i can define the trigger and the action.

What is the difference between: "event=[[sqrt(...)-1,diff(x(t),t)=...],[sqrt(...)-1,diff(y(t),t)=...]]" and "event=[[sqrt(...)-1,[diff(x(t),t)=...,diff(y(t),t)=...]]]", because i get different results, which one is the correct form?

Hi, I would like to numerically work out the profile of one expression (integral and BesselK function involved). But the computer was just jammed and came out nothing after long time waiting. I attach the worksheet below and maybe you could have a look at it or directly run it in your machine to check what is wrong, either my computer or the code itself. Thank you very much.

I am new to maple, and looking for som tourturial to get me started. My school dont offer any education in the program.

Can maple do the same things as matlab? i have a little program i wrote i matlab. Is it possible for me to write that i maple?

Hey Mapleprimes,

 I have a set of 3x4 Matrices and i need to filter some out, but cant find the right maple commands. Example Matrix:

[2 4 0]    row 1

[0 2 2]    row 2

[0 2 2]    row 3

[4 4 4]

row 2 = row 3

1. If all elements of a matrix have a common divider, such as 2 in the example matrix, I need to store the simplified matrix, meaning the one with all values divided by the common divider....

I am setting up a new machine.

I was running Maple 13 on another machine running Fedora Linux 13.   I don't remember if I had any problems setting it up, but it was running fine.

But I removed it from the old machine and installed it on the new machine which is running Fedora 14 Linux.

Maple 13 loads but I get a message from SELInux about a problem with Maples's mserver and execcstack.   ...

Hello!

I am rather new to maple and have a few questions considering one of my programs.

1. In my program I use 9 nested for loops. Despite trying to figure something out, I couldnt come up with a way of using less for loops.

2. In some of the for loops I want to start the loop from a variable of the for loop above it. Maple doesnt seem to be very happy about this.

3. I want to make a list of all the results produced by the for loops. However...

I have to prove a trig identity with Maple for class. It's rather simple, but I can't figure out how to get the right-hand side into the form I want. What I have is:

tan(x)^2*sin(x)^2 = sin(x)^4/cos(x)^2

I simply want to convert sin(x)^4/cos(x)^2 into tan(x)^2*sin(x)^2.

The conversion is apparent to anyone looking at it but I simply cannot figure out how to put it in the right form, and I can't change the left-hand...
