Is there a command the takes (A*B)^a and returns A^a*B^a ?

I tried expand and  simplify and also used assuming a>1 but without luck here...

I know this is very basic but I have monster product expressions that I need to be able to raise every term inside the parenthesis by the power so I can isolate some terms of interest.

Hello everybody !

Do you know any mean to find the number of iterations of the simplexe algorithm used in the Minimize pocedure?

Thank you very much for your help

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.

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
