Is there an easy way to find the limit of the following equations as Pec_i approches infinity.

 Equation 1

(Q*(R*S+1-S)/(1-R*R3*k*(1-R1)/C/Pec_i*S)*(H_vap+1/(1-exp(Pec_i)))*exp(C*Pec_i/(R*S+1-S)*(1-R*R3*k*(1-R1)/C/Pec_i*S)*S/k)-H_vap)*(1-exp(Pec_i*(1-S)/(R*S+1-S)*(1-R*R3*k*(1-R1)/C/Pec_i*S))) = 1;

 Equation 2

 Theta0/C = (exp(Pec_i/(R*S+1-S)*(1-R*R3*k*(1-R1)/C/Pec_i*S)*(1-S))-1)*(H_liq+1/(1-exp(-C/k*Pec_i/(R*S+1-S)*(1-R*R3*k*(1-R1)/C/Pec_i*S)*S)));

Does the series sum((-1)^floor(ln(n)^2)/n, n = 1 .. infinity) converge?

Please help me to make sense of the ways to use the simplify function. In this particular case Maple does some computation and gives me some huge output which I paste below. When I try to simplify the huge output Maple just hangs. But if I use varied commands of simplify detailed below such as simplify(huge_output,symbolic)  or  simplify(huge_output,size)  Maple gives me an output but none of the output are equal to each other and I also noticed that in one instance...

 Okay so I can see how to get the poles. But I have some further questions.

1) For beta AND Q both GREATER THAN 0 WHICH poles have positive imaginary part and is there a PROGRAMMATIC way of selecting these ones?

2) How do I calculate the residue at these poles? The approach given by Alec above seems useful and is much...

Dear fellow users,

I am trying to call Maple functions from Matlam .m file. How can I do it?

I am using Matlab 7.12 (R2011a) and Maple 12.

Thanks in advance..

I'm trying to write a for loop that will generate several procedures, which doesn't quite seem to work as expected.

Here is the sample code:

for j from 1 to 2 do
f[j]:=proc(x,y)
x+y^(j)
end proc;
od;

Then if you run the following, you get:

f[1](x,y) = x+y^3

f[2](x,y) = x+y^3

Whereas, I'd like to have:

f[1](x,y) = x + y^1

f[2](x,y) = x + y^2

Any suggestions on why the j value...

Hi,

I want to apply a complex differential operator to an expression "polynomial in the imaginary part * differential operator".

I have been unable to figure out how to do that using a formal operator and a concrete one that takes care of differentiating the polynomial.

In more detail:

Let $d$ be (my complex number is $x+iy$)

$d:=\frac{\partial}\partial x}- i\frac{\partial}{\partial y}$

which I want to apply to

$p(y) d$

dsolve event handling looks like a great tool, but I can't understand how it works and it's not sufficiently popular to google my way to examples online. There are two things I'd like to do: 1) interrupt the computation once some variable leaves a certain range, 2) interrupt the computation if the solver gets stuck into an infinite loop. Both are documented in the help, but I don't understand it. Suggestions welcome, thanks!

Hi,

I have 5 docs with datas (x,y), like this one : BEF1txt

I want to put the 5 graphs side by side (parallels linears fonctions in a 3D graph). So I added the z data, z=1 in this case, and BEF2 got z=2, etc... But I am not able to make the 3D plot with the 5 linears fonction side by side.

May you help me please?

Thanks

Hi--

I'm using Maple for an extensive research write up and need to somehow expand an extremely large function. The function is in terms of four variables, and each of those variables is either a function of x or a derivative of a function of x. I've attempted to use the "mtaylor" command, but it throws up an error when I try to input functions as my variables. I'm wondering if there's another way to do this. I've looked at using the "expand" command, but I don't see...

Hi, I am new to Maple, and, though I have scoured the internet and Maple's help, I have been unable to find a way to construct an element of F[x], where F is a finite field. Just to clarify, I am looking to construct a polynomial with variable x (eventually it will be multivariate, but I think I can extend to that easily), with coefficients from some finite field of size p^k, p and k being given.

I have seen a few examples online of people converting polynomials to...

hello!

i seem to have a problem with MatrixPower...

if i define a matrix such as

A:=([[-5,1],[-5,0]])

and use MatrixPower(A,k);

then i get the matrix A^k.

but, if fur example i do the following, i get an error:

A:=([[-5,1],[-5,0]]);

a:=exponential(A,1);

MatrixPower(a,k);

Error, (in LinearAlgebra:-MatrixPower) invalid input: LinearAlgebra:-MatrixPower expects its 1st argument, A, to be of type Matrix(square...

Could you tel me, is it possible to get free trial version of Maple 15?
