I'm trying to solve the differential equation.

Eq := diff(y(x), x, x) = -(x^2+1)*y(x)+K;

dsolve({Eq, y(-1) = 0, y(1) = 0}, y(x));

But this not work very well.

Best Regards,

I am using Maple 15, and before that Maple 8 and Maple 13. While using the versions 13 and 15, 

I come across with this problem; I cannot copy an output and use it as input. In Maple 8, I was able to do this but in 

these improved versions, it seems that it is not possible. Is there a way to solve this problem? I saw some answers about this

problem suggesting to change launch.ini file. But I could not apply this suggestion, since it is not permitted by the system. 

hello dear
how can i solve this three couplde pde?please help me

The word command for square root is sqrt.  What is the word command for square?  How to square all the values in a list?

Hi everyone, I'd like to know if it's possible to use the startup code editor as a general editor when writing large programs. It nicely recognizes keywords such as "if" and "proc" and you can indent code using TAB. However I'm not sure whether you can/should use it as a general editor to run code. I've read something about user-profiles related to the startup code but I just don't understand how it works.

I related two Text Area Components by using the codes "Do(%text_beta_radian=evalf(%text_beta_degress/180*Pi))".

I wanna know what codes can refresh the display of the text area component with name%text_beta_radian

after I change the input value of that%text_beta_degress?

Hey, I need to answer this question, not sure where to start..Any help/tips would be much appreciated....

Bob wants to explore the effect of changes in a, b and c on the function h, where h(x, y) = ∂ 2 /∂x∂y (ay sin(bx + c)). How should Bob do this so that if he redefines the variables a, b, or c later in the Maple session, subsequently computed function values h(x) use the new values of a, b, c?

that can run without maple using my own maple code?

And how about Maplesim? I heard that Maplesim can generate executable file

Hi all,

I'm new to Maple. Probably this is trivial, but how can I solve an inequality as e.g., the following

-2 <=  a/x <= 0

knowing that x > 0?

Thanks

Dear hope you will fine. I am try to make a program of square free factorization over a finite field whose alogrithm is below:

Algorithm: SFF (Square-Free Factorization)
  Input: A monic polynomial f in Fq[x]

Output: Square-free factorization of f

i←1; R ← 1; g ← f′;
  if g ≠ 0 then {
     c ← gcd(f, g);
     w ← f/c;
     while w ≠ 1 do {
           y ← gcd(w, c); z ← w/y;
           R ← R·zi; i ← i+1; 

           w ← y; c ← c/y }
     if c ≠ 1 then {
           c ← c1/p;

           Output(R·SFF(c)p) }

     else  Output(R)
  else {
           f ← f1/p;

           Output(SFF(f)p) }

  end.

The attached file my try to make this, please find and help me to complete this. I am waiting your kind response.

With my best regards and sincerely.

I want convert the integro differential equation to volterra integral equation by integration both side of integro-diff then subs in  initial condition 

intE := diff(u(x), x) = 1+x-x^2+int((x-t)*u(t), t = 0 .. x), u(0) = 3

How do it?

I need to replace the "MISSING" in MultiDiff := proc(f,n,x) ---MISSING--- end proc; so that MultiDiff(f,n,x) evaluates as f (n) (x) if f is a suitably differentiable function, n is a positive integer, and x is an undefined variable..F(n) being an nth derivitave..Not sure where to start..Any help appreciated

I was hoping to browse color results using a slider and text box. I see the "use DocumentTools" command, but was not able to get "use ColorTools" to allow execution of the "Color()" function. 

My slider "n" has the following code;

use DocumentTools in

Do(%outn=%n);
Do(%outrgb=my_rgb(%n));
use ColorTools in
Do(%outcolor=color_my_rgb(%n));
end use;
end use;

We are looking for enthusiastic Maple users to become Maple Ambassadors, to inspire and educate others about the benefits that Maple brings to education.

As an Ambassador, you will have the opportunity to influence the development of Maple through regular meetings with Maplesoft developers, get advance news of upcoming features and products, get assistance with Maple events on your campus, and more. In return, we ask that you do what you are probably already doing – sharing your experiences with Maple, answer questions on forums (like this one!), sharing your Maple applications, providing us with feedback, etc.

You can find more information and an application form at Maple Ambassador Program. We’re looking forward to hearing from you!

How equating the coefficient in the same power of x  

diff(u(x), x) = 1+int(u(t), t = 0 .. x), u(0) = 0

intE1 := subs({u(t) = sum(a[i]*t^i, i = 0 .. 3), u(x) = sum(a[i]*x^i, i = 0 .. 3)}, intE);
intE2 := eval(intE1);
intE3 := collect(intE2, x);
ans := zip(`=`, [coeffs(lhs(intE3)-rhs(intE3), [x, x^2, x^3, x^4], 't')], [seq(0, i = 1 .. nops([t]))]);

Shows me wrong I also want to find values of a[1] and a[2] and a[3] and a[4] without using my hand and from the initial condition a[0]=0?
