How do I solve canonical diffusion mathematical equation in Maple?

There is million items in list, 

what is the difference between seq and for loop ?

is seq faster than for loop?

it is very slow when running code below, how to speed up this part of code?

People im with error to show a plot, this is a wor for universty about mechanic materials, and i'm with this error... do not show the plot... before, i've a error because the variable x has values, and i've to unassign to have this.. without unassign, has error in domin of the plot... i dont know how to do this ! And ive to send the work today. 

Someone can help me about this?

how to eliminate the redundant solution (y^2-x*z, 0, -x^2+y*w)

from 3 of them?
eliminate({y,y^2-x*z,-z}, {x, y, z, w});
eliminate({-x,0,y}, {x, y, z});
eliminate({w,-x^2+y*w,-x}, {x, y, z, w});

Please help me to solve this integration

restart; with(LinearAlgebra); int(exp(-(ln(z/(snr*B^2))+4*sigma^2)^2/(32*sigma^2))*eta^2*(y/z)^((1/2)*eta^2-1)/(z*sqrt(32*Pi*sigma^2)*(2*sqrt(y*z))*(2*A[o]^(eta^2))), z, z = y/A[o]^2 .. infinity);

I have created and saved a MAPLE module in an .mla archive. The module contains three procedures A, B, C, where

A calls, B and C.  

Once the module library has been loaded, A acccepts inputs and generates outputs.

Is it possible to create a MAPLE player worksheet which calls the module and share it with a Maple Player (only) user, so that they can then supply the inputs and observe the outputs from A using the Maple Player programme components?

Can anyone help?

I have purchased Maple 2015 Student Edition a few months ago.  Now, I was about to buy MapleSim Student Edition and I saw that MapleSim include a license of Maple. 

If I buy MapleSim and Maple,  I would pay 198$ even if I could have bought only MapleSim and still get both products? 

Can I get MapleSim Student without Maple at a lower price? 

Maybe the version of Maple included in MapleSim has less features and that's why the cost of MapleSim and Maple are the same? 

Thanks in advance!  

I did some search on Google and on this website, but I haven't found anything. 

please demonstrate to me how to set up a maple document to solve a simple beam design from the scratch.

with(Groebner):
T := lexdeg([x,y,z],[e1,e2]);
intermsof1 := y;
intermsof2 := -z;
GB := Basis([e1-intermsof1, e2-intermsof2], 'tord',T);
result := NormalForm(y^2-x*z, GB,'tord', T);
result := NormalForm(y^2-x*z, GB, T);

originally Basis do not have error when without parameter 'tord'

after it has argument error, it has to be added extra parameter tord

NormalForm has the same error too.

i do not understand why it has error, how to solve?

i just want to express y^2-x*z in terms of y and -z

Where is the mapleclud palltte button ?   It is not in my Maple 16,  not in   mymaplecloud

How to upload a maple work sheet into  my maplecloud private  storage ?

consider quadratic equation ax^2+bx+c =0 :
the coefficients vary between -1 and +1 . just like this :
-1<a<+1 , -1<b<+1 , -1<c<+1 ;
how can some one proove that this equation should have real answers ?! can anybody help ? thanks in advance.

i am very new with Maple.

I have the following two equations:

x1=a-y1-d*y2;

x2=a-y2-d*y1;

I wish to express the first equation in terms of y1 and x2, so that

x1 = c - b*y1+d*x2;

where c=a-a*d and b=1-d^2. How can I get maple to rearrange the original equation x1 in term of y1, x2, c and b?

Hello Forum:

In the Programming Guide, section 14.3 (Programming Guide: Advanced Connectivity), the subsection `Runtime Environment Prerequisites' a sample script is given in order to set up the environment varibales MAPLE and LD_LIBRARY_PATH:

--8><--------------------------------------------------------------------------

#!/bin/sh
export MAPLE="/usr/local/maple"
. $MAPLE/bin/maple -norun
myapp $*

-----------------------------------------------------------------><8-----------

For testing, `my app $*' can be replaced by `printenv': it seems not to work with Maple 2015.

Any hint ?

Thanks in advance,

Jerome
