Maple 17 Questions and Posts

These are Posts and Questions associated with the product, Maple 17

I have a routine which returns a certain result. In the simplest case the result should be p[[1]].

The result is indeed p[[1]]. However, when I ask whether the result is equal to p[[1]], Maple says false.

Why does is not recognize these two things as being equal?

 

Dear all

` The aim of this code: to construct a non-abelian group of  odd order

such that the product of its elements not necessary identity element. 

symmetric_group.mw

But, the code doesn't display the elements. 

Thank you

This was very surprising!!

x:=3;
                               3
g:=x;h:=x^2;
                               3
                               9
subs(x=4,g);subs(x=4,h);
                               4
                               9

This is inconsistent! After g and h have been assigned values, they do not depend on x anymore, so g should not be turned into 4 by subs

Dear all

I have a box contains 3 red balls and 3 white balls, we select one ball three times and we define Z to be  the number of red balls selected. 
Since, we selected three times a ball and we count the number of red balls selcted after this experiment, we have 
Z(Omega)={0,1,2,3}

Now, How CAN I determine the sigma algebra generated by Z ( which is a random variable). 
The following code  calculate the sigma algebra generated by any subset  A subset of global set X , 
I would like to use it, to verify the descripted experiment in probability.

Dear all

I have a continuous piecewise function, but I can't evaluate its integral

thank you for your help

Dear all 
I have a function defined over the closed interval [ x[k], x[k+2] ] and zero elsewhere 
I would like to plot this sequence of function and compute an integral. 

I need your help to finish the attahced code, something is wrong. I can't  use piecewise funciton in loop and plot all functions in the same graph

thanks for your remaks and help

Hi 

Warm greetings.

Is it possible to solve the numerical scheme present in the below paper.

Anita Chaturvedi, Kokila Ramesh, and Vatsala G A. (2017). “A MATHEMATICAL APPROACH TO STUDY THE EFFECT OF POLLUTANTS/TOXICANTS IN AQUATIC ENVIRONMENT.” International Journal of Research - Granthaalayah, 5(4) RAST, 33-38.

Thank you.

Dear all

I know how can I use gauss seidel to solve a linear system.

But, how can we add chebychev acceleration.

Thank you 

Dear all

I have a set of three element, I want to apply each step of the definition of monotone class generated by a set to obtain the element of the monotone class generated by a given set. 

The definition and condition of monotone class is added in maple worksheet. 

I hope find some steps ( using maple) that will be applied later to other problem.

Dear all

I have the following code, 

for i to 6 do
for j to i do
F[i, j] :=  g(i+1)/g(j);
 end do;
end do;
How can display F as a full matrix  

Thak you for your help
