Hey MaplePrimes

I have a problem with opening some of my documents in maple. When i try to open them, a box pops up with the text "How do you want to open this file?" with the options "Maple Text, Plain Text, Maple Inputs". None of these options work (document is blank) and "Plain Text" and "Maple Inputs" causes maple to crash. Is it possible to recover the documents?

ps. when i try to upload one the documents this happens:

Hi all,

I attached a program here and the desire is the calculation of Nu.As you could see through the attached file, the F2(r) function contains an 'integral' which makes it difficult if I want to calculate F2(r=1) and it goes the same for D(F2)(r=\phi). So I firstly corrected the F2(r) function as FF2(r) in which the parameter R is calculated in the top of the file. Afte I replace the values of \phi and 1 in the FF2(r) not in F2(r) just because of the integral. The Nu is calculated finally, but it differs from the initial guess. How could I make a loop in order to correct the initial guess by replacing the first Nu calculated in the end of the program??

Ther is a problem and that is the "k" which must be entered in this part in each loop:

Digits:= 10:

K:=Nu->( k )

I do not know whether or not it is possible to change it so that the program identify the 'k' and replace it in the "K:=Nu->( k )" for k.

I must be missing something in my Fourier integral.  My understanding is that the sinc function is the transform of a square wave.  In the link below I am getting something slightly different.  I have the parameter tau to define relative to the period, T, to vary the width aspect ratio of the wave,  If tau=T I do get the sinc function.

What am I missing or is what I have correct?

  how can I find equation discribing elliptic intersections and use lagrange to show the higest and lowest value ?    g 

How can i solve this nonlinear equation using adomian decomposition method in maple? 

utt −uxx +u^2 = 6xt(x^2 −t^2)+x^6t^6

I'm having this

2+2;
Typesetting:-mn("4"), [4]

everytime I try a calculation. Could someone explain me what is this typesetting thing, and how can it be prevented? I haven't used Maple for a while and I cannot recall having seen it before. Thank you

Hello.

Please help me. I Have to solve some equations with Adomian Decomposition Method in Maple. But i don't know it.

I just know AGM, HPM and Perturbation Method in Maple.

please send me instructions and codes.

I'm sorry, I can't speak English well. I hope you understand what I mean.

thank you

hello , there , i want ask a Question ,

i have a vector result n hier , and there is a long part with ^1/2 (like unter) , which is not defined before , just from compute ,i want to replace this part with A, and have tried to use subs , but it didnt work . 

And i have tried to define it before compute, and then use subs , aber it also didnt work .

so how can i replace or define this part in the result?

thanks

Hi all, 

Is there anyone who could solve this equaiton? I think there is no solution!!!!

Good day!

I am working to solve a double series (LP  minimization) problem of the form 

z = add(add(x[i,j]*y[i,j]*z[j], j=1..6), i=1..3).

However, this returns a set [ ]. 

Since LPSolve does not operate on a set (removing the brackets manually will enable LPSolve to obtain the solution), can anyone suggest what is wrong with the structure of this z-equation? x, y are matrices and z is a column vector.

Thanks!

Hello everyone!

Total beginner here. So far I am just using the right click options in Maple,  and worked wonderfully until now.

Two questions for some charitable sould out there:

1) I have a system of inequalities that I need to solve. I am interested in the *conditions between the variables under which a given inequality is satisfied*.

Using the "solve" command I only get a few of these. Do you know any script that can obtain more solutions? 

2) I have some (long) equations and want to be able to visualize them in different ways to make sense of it. So far I have only been using "simplify" and "combine", but it keeps on returning the same result even if I can see there are other possible ways of factoring the equation. How can I tell Maple to give me "different optiosn" as to visualize the equation?

Thank you all!!

Is there a way in Maple to evaluate the following integral - where the "w" are set to go to zero to avoid singularities? B.t.w. Maple just returns the integral unevaluated with or without the "w" with the simple "int" command. 

int(ln(((p1-p3)^2+w^2)/(p1+p3)^(w^2+2))*ln(((p1-p4)^2+w^2)/((p1+p4)^2+w^2))*sin(p1)/(p1*p3*p4), p1 = 0 .. infinity);

or even

int(ln(((p1-p3)^2+w^2)/(p1+p3)^(w^2+2))*ln(((p1-p4)^2+w^2)/((p1+p4)^2+w^2))*sin(p1)/(p1*p3*p4), p1 = 0 .. 100, numeric);

Here's something neat to be done in Maple. 
This anaglyph or stereo image uses the red green glasses to make the model appear more 3 dimensional.  The static-non-stereo image of the animated plot below is done in maple by plot3d(sin(x*y)^2,x=-2..2,y=-2..2,scaling=constrained)

Anyone?

hi

Dear Maple  users,

I am facing the memory allocation problem while calculating the inverse Laplace transformation of a big expression. I have many such terms (401) and I am importing them from a text file.

For an individual term itself, Maple consumes huge memory but at the end, it is able to calculate it in about an hour. I want to automate the process of reading and writing the terms one by one from the different text files. While doing so, maple eats a lot of memory and I see the error msg

"Error, (in expand/bigprod) Maple was unable to allocate enough memory to complete this computation.
Please see ?alloc "

Is there a way to do so? The maple file is attached.
