Hi, I need some help with my code. I got the code that you can see below:

> with(DEtools);

> with(plots);

> cc := Array(["Blue", "Red", "DarkGoldenrod", "Black", "LimeGreen", "DarkMagenta", "Indigo"]);

> ll := Array(...

Hello

I couldn't make plot3d in my Maple code please see the file I attached it and let me know any idea how can I make plot it in 3D

Thanks

Hello,I'm trying to sort a list of symbols respecting some assumptions I have made about them. For example, I'd like to assume that 0<x<1, and I would like [x, x^2, x^3] to be sorted into [x^3, x^2, x]. How would I accomplish that? Making an assumption with assume() does not affect anything, as the sort() function does not seem to be actually comparing the values of symbols (only numeric values). Any help will be appreciated.Thank you.

I have here Maple proc, but it doesn't work. I am try to solve this equation pde := diff(u(t, x), t, t)-(diff(u(t, x), x, x))+x^2*u(t, x);

with 3 piont known , we have stencil:=u(i,j)=-u(i-1,j-1)+(1-h^2/8*v(h/2*(j-i-1))^2)*u(i,j-1)+(1-h^2/8*v(h/2*(j-i+1))^2)*u(i-1,j);please see the file I attached here Thank you

Hello everyone,

I saw a question on a different forum related to the stability of the numerical solution of a coupled ode system. The original question was about the convergence of the far field condition (infinity) for some specific values of the different parameters involved. For the details please see the link below

Hello I wish to solve nonlinear PDE equation numerically in u & v coordinate . where u=t-x, v=t+x . we note x=(v-u)/2.. pde := diff(u(t,x),t,t) - diff(u(t,x),x,x) + x^2*u(t,x);

We need only initial condition let f(u)=sech(u) & g(v)=sech(v). So u((i,0)=f(ih), u(0,j)=g(jh)

we summe step size of time j = step size of spatial i .

the stencil we use ,

In my maple 16 the following is returning FAIL. Why ? and what is the correct way to do the following.

restart:

assume(n::posint):

is(n^2<=2^n);

Regards!

Please help?

I tried this on maple: eps1 := [0, 1/5, 2/5, 3/5, 4/5, 1]: start1 := 2.3: base1 := 1.1: for i from 1 to 6 do R := start1*base1**0: points1[i] := [R, evalf(eval(mH, {M=1, r=R, epsilon = eps1[i]}))]: for a from 1 to 20 do R := start1*base1**a: points1[i] := points1[i], [R, evalf(eval(mH, {M=1, r=R, epsilon = eps1[i]}))]:...

Hello,

I have a question about 'combining' procedures, in like: I would like to write a procedure which refers to a formula containing already a procedure.I know somebody already posted a sort of similar post in 2009, http://www.mapleprimes.com/questions/36874-Calling-Procedure-Inside-Another-Procedure, but I'm missing the point of what's happening over there...sorry for that.

I just would like to know a general form of how to use a procedure 'inside' another procedure.

Well, in my case I have a formula (let's say 'equation1') containing a procedure which eventually draws a line. Later in my worksheet I use a formula ('equation 2') which is a procedure too, in which I want to substitute a parameter into 'equation1'. But because 'equation1' already contains a procedure I don't know how to solve this situation.

It's pretty hard to explain it on paper, but I hope it's clear.

I've done the procedures for answering the questions but i don't know how to go about calculating f(6) and f(15).

Hi, this question requires the use of with(geom3d): package and i don't know how to go about answering it.

Hello dear,

I want to plot a piecewise function.

The code is

restart:with(plots):

lambda0:=PL-R3*x;

Psi0:=PL+R3*S0*(R1-1)-R1*R3*x;

S0:=(Q-1)/Q;

P:=piecewise(x<S0,lambda0,x>S0,Psi0);

R3=-5,k=4,R1=0.0006,Q=1.2

I want to plot P vs x (0..1) vs PL (0..1).

HelloI have Mathematica code(notebook) I want to convert it to Maple code (worksheet) Thanks

Hi,

The maple 16 installed on my win7 system does not work because its gui worksheet does not accept any symbol input (except the plus sign). For example, the cursor become frozen once a minus sign is input. The classical worksheet works well.
