Hi,

I've given this problem (not exactly in this form though- therefore this is not giving the same problem again) in this forum months ago, and got a valuable suggestion.

Now, I want to take a different approach for the solution, I want to use root finding (say, fsolve ). Can anybody please tell me why the fsolve isn't working, how I can fix it ?

If possible, please send me a worksheet.  

The problem is -------  

Hi,

I asked a similar question some time ago : http://www.mapleprimes.com/questions/123925-Shortcut-Key-AltShiftF6.

I'm still on Maple 13, and I still have not found a way to switch between tabs/windows using the keyboard.I am in the one Maple session (ie I haven't started a new one).

I tried all suggested combinations, including all combinations of Ctrl, Alt and Shift...

 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'm writing a maplet and I would like to put in my MathMLViewer two equations. Each equation in different line. How can I do this using MathML[Export]() while setting the value of MathMLViewer ?

Is there a way to create an interactive plot, and put it in a Maplet, so I could get onclick coordinates and display some points there on my plot ? I checked Maple help and I didn't find any onclick event for plot or Maplets,Elements,Plotter but I found something called PlotComponent and there are some options like clickx, clicky. Can I use it somehow in Maplet, or maybe there's another solution ?

I would like to save a simple plot to jpeg file on my hard disk. I've got a Maplet, and a Button which looks like that

Button['SIM']
 (
     "Save image",
     onclick=Evaluate('function'='saveImage()')
)

and a procedure:

saveImage := proc()

   plotsetup('jpeg', 'plotoutput'="plot.jpeg", 'plotoptions'="portrait,noborder");
   plot3d(sin(x)+cos(y), x=0..2*Pi, y=0..2*Pi, 'axes'='boxed');

Hi,  if i have a matrix 4x4 as

A=[I          Y        -X        aX

     bY        Z         o          o

      X^T     O^T     0         0

       o^T  O^T       0         q ]   

Hi,    I have the following    

for i from 1 to 100 do    x[i]:=cos(θ[i]);     y[i]:=sin(θ[i])  end do; 

Now I want to find the first and second derivatives for x[i] and y[i] which are

for i from 1 to 100 do     x1dot[i]:=-sin(θ[i]);     y1dot[i]:=cos(θ[i]); 

                         ...

How can I create using Maplet a window that is not modal, so I could minimize or maximize it (I know what to do to make it resizable and that's not the question I would like to ask).

This simple example creates modal window with no minimize and no maximize button:

> with(Maplets[Elements]);
> maplet := Maplet(Window([]));
> Maplets[Display](maplet);

Is there an option to set for a Window or maybe I should change some settings in Maple 13 that I'm using ?

Hi,

I work on a dynamic programming problem and I must used the result of a maximization function, but I can not

I'm trying to approximate points with a function of certain form with Statistics[NonlinearFit]. I expect the graph in the second example to be closely approximate of the points, just like the first graph. For some reason, the second graph is way off. Seems like a bug. Any suggestions are highly appreciated.

Here is the code

plotApprox := proc(listName)
    local X, Y, convModel, modList;

how can i overcome the error that i am being given for the problem below 3*t*d(t,x(t),diff(x(t),t))² = 0

Hello everybody,

I represented a polynomial P type:
P := a + b*x + c*x^2-d*y + e*y^2 + f*x*y
(where a, b, c, d, e, d, are real)

using fucntion pointplot3D
G1 := plot3d(P, x = 0 .. 5, y = -0,5 .. 1);
display(G1);

I represented this polynomial which look like a paraboloid.

I'm just wondering if I can animate continuously...

I am having trouble identifying all the possible roots existing in the range specified.

In the file attached i have a non-linear set of equations that are solved for "w" value specified...but fsolve provides solutions only at certain values of "w" , does it mean there is no solution for other data points ?...or is there a way to find out all possible solutions for each value of "w"

HI,

I want to make a program that will list the twin primes.  Is it possible to implement the isprime function in C?  I want to be able to run this program on a computer that doesn't have Maple installed.  Here is my code -

twinprimes := proc (maxnum)
local a;
description "output the twin primes less than maxnum";
printf("%12d", 3);
for a from 6 by 6 to maxnum do
if `and`(isprime(a-1) = true, isprime(a+1) = true)
then printf("%12d", a-1) end if
