I’ve created a basic model of a two-lane road.

i am looking for a command adjoint a ODE, to check whether my understanding of adjoint correct or not, when i find one example different from my understanding as follows

u*diff(Y,t) - diff(U,t) + diff(y,t)*U = 0 where uppercase and lowercase are different

why after adjoint is

Y -> -u*diff(lambda,t) - diff(u,t)*lambda = miu1
U -> diff(lambda,t) + diff(y,t)*lambda = miu2

why not

Y -> u*diff(lambda,t) = miu1
U -> -diff(lambda,t) + diff(y,t)*lambda = miu2

I installed Maple 15 for windows 64 bit on my pc but I have a problem with worksheet in its.

Worksheet isnt on my software.

u''-w^2+Eu^2=0,           u(0)=A,  u'(0)=0

How can I solve this question the variational iteration method with maple.please help me!

hi 

if I have two partition Pi and Pi 'I want to know the decomposition of Pi' 

Attached are results I obtained in MAPLE 12.  Can anyone explain the contradiction?

In short, if I sum from n = 0 to some integer I get a FALSE when testing the equality, which is what I would EXPECT.  However, if I change the integer to a variable to represent that integer such as m--> the result is TRUE?

Note the change in the variable of beta to alpha inside the series expression within the parentheses.

regards

Write a procedure that determines the solutions of a quadratic equation from inputs a, b and c by using the discriminant and the quadratic formula. The quadratic equation procedure should be able to solve all cases: invalid input, linear case, real and complex roots. The procedure should also plot the given equation.

Hi,

I want to compute a system of linear equations when they are provided through a matrix product, and the solutions should be some numbers (rational) between 0 and 1, and one of them could be any rational number. Also, I obtain the matrix of coefficients by recursion; I mean, I have a ''for loop" in which I find recursively the matrix of coefficients, and then in each step of loop I solve the system of equations with this coefficients.

I use Maple 13. The...

Hello. I wanted to solve a parametric 16*16 determinant. My first question is, whether or not it can be solved?! after that when I tried to open my work in progress I got the following message: "
There were problems during the loading process. Your worksheet may be incomplete". Could someone help me recorver my work? Thanks in advance.

Hello,

we have to create program which shows chemical concentration changes, but this concentration depends on time and distance along the longitudinal axis. So we have to put numbers into the left side 41x41 matrix from 3 equations:

A:=1, B:=1,E:=0.2, Δx:=0.25,Δt:=0.025.


first when i=0;

Based on the title, once again I'll mention that the programm that I have been made by using

Maple14 could not run faster.

The function of Maple should be running effectively compared to others.

Hereby, I'll attach the programm for your further action.

That's all, thank you.

i creat an animation in maple , and want to export it then use it in other presentation, such as word or powerpoint.

i try to save the animation, but fail, it is only one static picture, so how can i export it dymaticlally.

Hello to everyone

Pls help,urgent....

I need to draw the deformation of one story building (for simplicity, 4 columns and 2 floors) whose columns and floors  under influence of external load acting to the left of the building at its intersection point undergo the deform shape like S . So means that when the building moves to the right its intersection point of column and floor has some small rotation.

I am new to Maple environment...

When maple does gauss elimination for matrice(student linalg). In "edit matrice" can i solve for x1,x2,x3..?
