How do you plot the following parametric equation (equation of an ellipse) in the same graph

Hi there,

Unfortunately I don't have access to Maple because I am away from my office for the week, but I need a

system of linear equations solved. Can someone please solve it for me and post the solutions (if any)?

The system is:

a_1 x_1 + b_1 x_2 + c_1 x_3 + d_1 x_4 = e_1 + e_4

a_2 x_1 + b_2 x_2 + c_2 x_3 + d_2 x_4 = e_2

a_3 x_1 + b_3 x_2 + c_3 x_3 + d_3 x_4 = 0

a_4 x_1 + b_4 x_2 + c_4 x_3 + d_4 x_4 = e_1 + e_4

I am supposed to adjust the code my teacher gave us for a project. The only problem is I dont know anything about maple or much about what I am supposed to do. I tried copying and pasting the code but I couldn't.

The assignment says to adjust the code to incorporate variable window size. There is a place in the code where it says insert code here and the teacher said it shouldn't need more than like 8 lines of code.

If anybody thinks they they can help I will be more then happy to forward you the email.

working on my exam notes for tomorrow, I get this...

and only 1/3 or so of my document opens... anyone that can help me out here..?  

I use Maple 17... 

I want to choose four points A, B, C, D on the sphere  (x-2)^2 + (y-4)^2 +(z-6)^2 -81=0 from the list L so that there are not any the right triangle are formed from the points A, B, C, D. How to get it? I tried

> restart:

with(geom3d):

eqS:=Equation(sphere(S,(x-2)^2 + (y-4)^2 +(z-6)^2 -81=0,[x,y,z],'centername'=T)):

L:=[]:

I am also having trouble with limits when I have indexed
variables.   That is, how do I tell Maple to assume every element of
an indexed variable is positive?

Here, I show that normal limits work.

                                1/2         1/2

                          1/2 Pi    - 1/2 Pi    erf(3)

Hello,

I have found numerous ways of plotting PDEs, but I am trying to ask Maple to calculate the simple analytical solution of one.

Now, Maple is very happy to solve the following with one initial condition:

restart;
with(PDEtools);

pde := diff(u(z, t), t)+c*(diff(u(z, t), z)) = A;
IBC := (u(z, 0) = f(z));

sys:=[pde,IBC];

ans:=pdsolve(sys); 


However, when we take, 
IBC := (u(z, 0) = f(z), D[1](u)(0, t) = 0, D[1](u)(-h, t) = 0);

Recently I was presented with some code that had a seq command that used i as the index variable. While this code had been used in a number of applicaitons, it was now giving trouble.

seq( i^2, i=1..10 );
Error, illegal use of an object as a name

After a stroke of fortune it was discovered that the problem was that Maple's imaginary unit had been changed from I to i. Given that this change was made, the error message now made sense.

The general formula of GHR (Gazis-Herman-Rothery), the most well known car following model, is given by

an - acceleration of vehicle n implemented at time t
v - speed of follower vehicle
deltax and deltav - relative spacing and speeds respectively between follower and leader vehicle at a

Hello,

I have currently trouble running existing C-code in a new Linux (64 bit) system with Maple16. I have code that used work just fine, now it fails to evaluate. As an example, statements like

EvalMapleStatement(kv,"1+1+2^3;");

still work as expected and return a number. However, code like

EvalMapleStatement(kv,"int(x, x=0..1);");

returns int(x, x=0..1), i.e. a string, which causes my program to crash, because a number is expected.

Hi,

     So I'm having a little trouble with command-line Maple 16 on Ubuntu 12.04, 64-bit.  I can enter the commands

plotsetup(gif, plotoutput="testing.gif");
plot3d(sin(x)*exp(y), x=0..5,y =0..5):

and a .gif file will be created with the graph. However, if I save this as a text file "testing.txt" and run it via the terminal command

maple testing.txt

it does not save the graph. Any idea why this is?

So far I've tried

Hello,

Please when i solve a list of equation with fsolve i get a list of result:

How to copy maple output equation in word such that in word 2003  we can edit the equation

A1:=(-exp(-alpha*x))/(2*eta^3);

thanks
