how to solve this partial differential equation  :

d/dx[(1+e*T)dT/dx]+P*dT/dx-B*T=0

e ,p ,b are constants and t is temperature.

plz help in finding a solution for this differential...or the closest method to simplifying it...

I am trying to overload the "." operator (noncommutative product) to handle objects I have implemented as records. Each record contains a matrix R and a parameter l. A.B will produce a new record where l is l_A+l_B and R is R_A.R_B, "." here being the normal matrix product (and I use LinearAlgebra:-Multiply in the body of my procedure for this). The objects A and B are of type 'Element', which I have defined (using AddType) and which works.

I implemented the procedure...

Sorry about that I was not aware of this problem.  I have written now in text as follows:

In the following there needs to be two if conditions applied i.e. one for the k / p = 1,3,5,7   and second

if (m*Pi = k*bo)    and also same for if (m*p is not equal to k*bo)

When I try to solve it says invalid if statement termination:

Hi all,

I need your kind suggestion to solve the equation for odd ratio.  I am attaching Maple file for the purpose.   I have to evaluate a function for odd ratio and for other values its zero.  I need help in assigning this odd and even ration to the function.  k can vary from 1...15, depending on ratio.

I shall be very thankful for your kind responses.

what is the window use for maple 16: vista, xp, or win 7?

Question 1. After googled, x*diff(F,t)+t*diff(F,x) for two variables, how about three variables or general ?

Question 2.

if deal with on variables case using the example in

http://demonstrations.wolfram.com/AFunctionInvariantUnderAGroupOfTransformations/

F := (x^2-x+1)^3/((x^2)*(x-1)^2)-y;
G:=y*diff(F,x)=0;
sol:=solve(G,y);

F(H)-F = 0
sol:=solve(F,x);
H := simplify(subs(y=F, sol[1]));

all above code can...

Hi all,

I am trying to solve the equation for values k=1 to 10,  but the issue is when I put k=1 equation goes to infinity.  I am attaching Maple file for your kind consideration.  I have also included an example which may help you to answer.  I couldn't understood how its done.

Dear Markiyan,

Since you took the time to think about this problem and help me, I think I should ask my problem in full instead of just part of it. I believe, then, you will perhaps agree that the issue at hand is not a prejudice against a procedure. By all means, I am interested in solving the problem with ANY method. In my...

Hello! I am running the same piece of maple code on different machines, and I have noticed that the powerset function returns the sets in a different order. For example,

Maple 11 (X86 64 LINUX)

> powerset(3);
            {{}, {1, 2, 3}, {2, 3}, {3}, {1, 3}, {1}, {2}, {1, 2}}

Maple 14

> powerset(3);
            {{}, {1}, {2},...

Hello Maple experts,

 I want to find out k-th probability (denoted by c(k)) which is expressed as an integration of summation for values ranging from j=0 to k. The function is very complicated , I have attached the PDF for expressing the mathematical term properly.

I am able to find out the c(k) for a given value of k, if k is specified in the beginning of the maple program. But I am unable to make it generic form of k.

I have also attached the...

Hi all,

I am stuck in defining two conditions for the equation.  I am attaching Maple file for your kind consideration.

Actually I want to assign the value of k=1, and when k is not =1, for G11(k).

I shall be very thankful for your kind replies.

Best Regards

Hello, Maple wizards.

Can we talk about how to perform arithmetic efficiently on submatrices? To illustrate, let matrices A and B be represented by a block structure using submatrices, so that A and B are

A11  A12
A21  A22

and

B11 B12
B21 B22

respectively. I want to efficiently replace the lower submatrix A21 A22  with A21+B21   A22+B22.

Here's the catch (to me, anyway): the indices representing...

hi

consider the following ode

eq1:=diff(f(x),x$3)+f(x)*diff(f(x),x$2)+diff(f(x),x$1)^2;

subject to thease boundary condition

f(a)=0,D(f)(b)=0,D(D(f))(0)=0

where

b= infinity (in computational domain b=10 is acceptable )

the exact solution of ode is

f(x)=tanh(x/2)

but when i want to solve it with Dsolve, maple get the zero. how can i use this ode in maple

thanks

I am a transplant from to Mathematica to Maple and still getting used to things. Could somebody please help me finding the maximum of f with repect to the constraints and with the variables below. I keep getting  syntax error, no matter how many times I check the documentation page. Thank you very much
