Hello, I am new here and hope to post in the right section. I am encountering a few problems with learning myself how to construct larger maplets. The first problem regards the simple enabling / disabling of a button with a check box. See the example code below. If the checkbox is selected, I would like to have the button enabled, and if the checkbox is not selected, it should be disabled. Simple as that, but I can't find out what I need to do to get the code working. The 'CB1'('value') statement is not of the correct type??

Hello Everybody I am very new to Maple and have a problem that I need help to. I have an equation and a plot in Maple that I need outputted to Excel for plotting in Excel. Is there any way to output the relevant x-y coordinates to a data file so that I can plot in Excel or can I directly output the x-y data straight into excel? Here is an example of the last few lines of Maple code. What lines of code should I add to this to get what I want? > t := .15; > r1 := 5;

Hello Everyone

I wonder if anybody can help. I'm trying to use maple to find the largest mutual sequences of digits in two lists of 5000 dozenal (base 12) digits (I've tried searching on Maple help for a function that would do this, but am having trouble as I'm not sure what this would be called - a fellow music student suggested correlation - would this be correct?)

On a small scale, the function I am looking for would return the following sequence:

[5, A, 3, 8, 9]

from the example lists

A:= [1, 7, 8, 5, A, 3, 8, 9, B, 4] and

I'm trying to write a code that does the following...
 

It takes a polynomial of the form a*x + b*x + c and cycles through vales of x from say, 1 to 100 then tells me how many primes i get. But what i want to do is start with x + x + 1 and then do x + x + 2.. etc for values of a,b,c from again, 1-100.

The following code will print all polys of the form a*x + b*x + c for a,b,c from 1-100.

for a to 100 do

for b to 100 do

for c to 100 do

print(a*x + b*x + c)

Bonsoir! Je cherche à déterminer la hauteur maximale atteinte par une fusée à eau, en fonction du volume d'eau initiale. Je dispose déjà de deux équations, l'une reliant la variation de masse à la vitesse d'éjection de l'eau, l'autre résultant du principe fondamental de la dynamique. Neanmoins, il me semble que je devrais avoir une (ou plusieurs ) equations reliant la hauteur aux paramètres des 2 equations citées précedemment.

Pourriez-vous m'aider?

Is there  a rule similar to cos(n*pi) = -1^(n) for sin(n*pi/2)?

I know for the sin(n*pin/2) it's zero when n is even.

How would a similar rule look for odd integers n, or for all integers n for the case of the sine function?

thanks,

dc

I just use the Maple for one month, I want to use the Graph theory Draw a graph(networks) with 70 vertex, but the arrow of edges is always near  the beging point of 

arc, which lead to the arrow can't  be seen clearly, I want to change the sytle of edges by changing the arrow position , but I don't find a correct method , can anyone help me ? Thank you very much!  

I am a graduate student who is currently enrolled for a graduate course in Computer Algebra during the Fall semester. I have spoken to the instructor of the course and he suggests that I should gain proficiency with Maple over the Summer. With that in mind, does anybody know of any resources that may be useful in gaining proficiency with Maple? Thank you for your cooperation.

Hi everyone..

I am new learner in maple program. I have quadratic exercise and It is important for me to sove it perfect. I tried to solve it but I am

not sure about me answers.I need your help please. 

This is the question:

 - Given the equations: y=2(x-4)^2-18 and y=2x^2-8x-16, answer the questions below:

1- Find the y-intercept for each of functions

 

2-Find the zeros of of both functions

 

3- Find their General and vertex from respectively.

 

I have this formula:g:=Sum(Sum(Sum(n!/m!/j!/k!*(1+p/20-c-h)^m*(h-p/20)^j*c^k*( j*(w+r*p)+Sum( k!/(k-l)!/l!*(c+h-p/20)^l*(1+p/20-c-h)^(k-l)*( (k-l)*(w+r*p)+l*(w+r*p)*X),l=0..k)),k=n-m-j..n-m-j),j=0..n-m),m=0..n);

which I realized was silly after a few minutes of looking at it, that I should be able to reduce it to a double and triple sum instead of a triple and quadruple sum. However: when I got to reduce the triple to the double, with the formula

Hi,

I am trying to get the right eigenvectors of a matrix dFxdU (see file attached)

Hi

I have derived some eigenvalues and eigenfunctions in this maplesheet. But in the subsection "check to make sure

the right eigenvectors are correct" , Maple is not converting the value of lambdax[i]=u or u-c and hence it returns me an output

of the form :

I have been unable to get any sensible output from the SphericalY function in MAPLE 12. With the command:  testp:=SphericalY(1,0,phi,theta), for example, the output line is just the command line. The only input parameter list that seems to give anything else is (0,0,0,0), which gives testp=0.

Hi,

I am trying to see that two square matrices are same or not in Maple. So I am subtracting one from other and expecting to see a 0 matrix of the same size.

But instead of returning a 0 matrix or some other result, it outputs a string "ee". Does

anyone know what "ee" means?

Thanks

Hi,

I am trying to calculate the eigenvalues of the matrix dFxdU (see file attached) and Maple is giving me the message

"Error, (in content/polynom) general case of floats not handled"

This is weird as dFxdU is just a simplified form of dFdU derived earlier in the maplesheet and when I try to

get the eigenvalues of dFdU, it does it fine.
