Hi,

I'm trying to modify the size of the window where an animation is shown. Tipically, this window has axis going from xmin to xmax and ymin to ymax but this causes some scaling problems when xmax-xmin>>ymax-ymin. I would like to focus in a certain region of my animation and change this viewpoint depending on the position of the elements of the animation. Can anybody help me?

This is my code:

> tf := 5;
> nfr := 201;

I have a huge PDE system included reaction-diffusion system with 4 independent and 12 independent variables. I read on the maple help for pdsolve/numeric/method. I found it is only for single partial differential equations in two independent variables. Is there anyone knows the ability of Maple for such a system?

qRacah := qhyperterm([q^(-x), alpha*q^(-x)/(gamma*delta)], [alpha*q], q, gamma*delta*q^(x+1)*t, k)*qhyperterm([beta*delta*q^(x+1), gamma*q^(x+1)], [beta*q], q, q^(-x)*t, k);

i use inverse laplace to transform ordinary generating function into exponential generating function

can not further evaluated

i do not know whether x is main variable or q is main variable or both are.

ff := eval(subs(x=0, exponential_genfun));

Hi,

I am aplying a simple energie balance with some simplification, and i am implementing it on maplesim.

The component has the following equations:

Am i missing something? Do i need any aditional equation to maplesim know to where should the fluid be moving when Qjacto is positive or negative? Why do i have...

Hi,

I am trying to perform a simple model of the entrainment of air in a jet by aplying energy emand momentum balances to the injector and flute. But i am having doubts on how to prescribe pressure on a point. This is the equations of the component Injector:

I want to solve 4 nonlinear equation using maple. I want to find many roots of this 4 nonlinear equation.

I have no idea about initial condition so I use 4 for initial condition. my program is as follow:

f1:=nonlinear equation1(include variable q1,q2,p1,p2);

f2:=nonlinear equation2(include variable q1,q2,p1,p2);

f3:=nonlinear equation3(include variable q1,q2,p1,p2);

f4:=nonlinear equation4(include variable q1,q2,p1,p2);

MAPLE Users,

Suppose I have a set of points in some N-dimensional space.  I would like to obtain a simple polynomial that

best fits the data.  I do not know in advance the form of the function, but a simple function that does not overfit

the data would probably be OK.  By "simple" I mean the smallest degree with or without cross-terms that gives a

decent fit.  My data set will typically be an external comma or tab separated text file.

Hi,

     So I'm trying to animate a ball moving around in a moving circle. I can do a sequence of points, and a sequence of static circles which works okay but I'd like a continuous animation. Here is the points where the ball hits the circle (x,y) position and the times (t).  and the animation of the circle

Here is , seemingly simple task:
In the Euclidean plane are given two sets, each with 4 points. It is known that all possible pairwise distances between the points of the first set coincide with all possible pairwise distances between the points of the second set, ie we obtain two sets of numbers, in each of which six numbers. Of course, the numbers in each numeric set can be repeated (such sets are called multisets).  Can we say that there is an isometry of...

Having read the above I decided to try it on a substitution problem I had last year on a set of equations. Work sheet containe an example. I successifuly applied algsubs to the problem. It can be slow and their is no easy way I see to know when the substitution is complete. so what I did go round the loop 2, 3, 4, 5 times. Crude!

Decided to try "side relations" with simplify here but it comes out with a totally different answer (not correct).

Could somebody explain why?

I'm not sure this topic has ever come up.  I cannot find a way to output strikethrough characters.  Underline and subscript will get you strikethrough characters.  Is there a way to produce strikethrough output?

Can you make geometric figures that hold a particular area within a given perimeter of 12 matches

My attempt was to start at origin 0,0 and move up 1 unit (a,b) and then 1 unit up or to the right (c,d) etc ... until you enclose the required area (defined by linear spline) s.t. perimeter =12. but it doesn't really work

I recently get a new macbook pro with retina display. Unfortunately Maple 16 seems to be not retina ready. Searching the net I found a tool called retinizer. Using it Maple 16 seems to be displaying a little better, but still the outputs of calculations looks blured. however, whenever certain texts are selected, the whole Maple window display becomes very sharp, so I guess Maple is somehow retina ready but this functionality is disabled by default. Checking the "Get Info" window...

I've several versions behind but I getting a strange behavior. I created an assignment using the eco0 question bank. Later this assignment was passed to a class a semester later. The question bank eco0 was updated. As the instructor, using the review button on the assignment shows the new version of the question bank. As a student, the assignments are getting the old question bank question.  The students didn't start the assignment until after the questionbank change.(I think I'm using version 4.0.) 

I need the button that will change the content (list) of a ListBox. When I create such Maplet, ListBox behaves very strange! The ListBox sometimes shows the list after the button click, but sometimes the list disappears. 

The code below reproduces this strange behavior. Just click the button several times.

getObjects := proc()
