hi; using the animate3d command i would like to create a kind of reference plain, i.e. i would like to insert a plain at a certain value to figure out at which "point" the animated surface cuts through this reference plain. it should look like the static version shown in the linked worksheet: View 1682_cp solution.mw on MapleNet or Download 1682_cp solution.mw

Hi friends, In my maple procedure I m calculating large amount of point then I m plotting them. Although I don’t know how many points will be calculated, I have a logical upper bound for number of points. I was using the method 1: for i from 1 to N do if something is okey then x := ... y := ... data := [op(data), [x,y]]: end if; od: but I have relalized that this is really slow. Then I started to use Method 2: data := array(1..N): j := 0; for i from 1 to N do if something is okey then x := ... y := ... j := j + 1; data[j] := [x,y]:

I have a problem with my project. It’s a mathematic problem of least square. And the mathematic formula maybe complex to me. So I have no idea to solve this question with MAPLE,because I learn maple a few day by myself, but the time of project will end in follow months. This is too bad for me. Maybe I need some help, but I don’t know who knew the maple around me. The last hope is the kinds of friend of mapleprimes.com . if you have interesting of my question,you can download my upload files. best regard's Download 1984_I have a problem with my project.doc

Hello, I have a 1.5 million digit string and would like to cube it. I believe I have succeeded in reading the text file, but don't quite have the language right for manipulating and sending back to text. Thanks in advance, Dan

Suppose we have a column vector B of n elements. Whats the simplest code for creating n x n Matrix A whose off diagonal elements are 0 and whose diagonal elements are the elements of B?

I have developed a Maplet tutorial in which the output of the Maplet Evaluate is an X-Y plot displayed using the Maplet Plotter element. I would also like the Maplet to display the numerical X-Y data in a format that would allow the students to simply copy and paste the data directly into an Excel document so that they can carry out additional analysis of the data. Any suggestions?

Hi, I'm trying to get maple to output the numerical answer, from a call to dsolve, to an external txt file; but I'm having a bit of trouble. I want to do this so that I may then plot the results in an external program like easy-plot, or just analyse them. I'm using a "read" command in Maple to read in a procedure from a txt file (shown below), which I then execute in Maple: #Utilise prime notation for derivatives wrt t: with(PDEtools, declare): with(plots): declare(y(t), prime=t, quiet): #Also shorten output notation: alias(y=y(t),y0=y(0),yp0=D(y)(0)): #define the ODE: ODE:=diff(y,[t$2])-(1-y^2)*diff(y,t)+y=0;

When using Maple 10's clickable capabilities one easily gets the results requested. However at the end of a long session the user has a long list of generated results , but it is not easy to recall what was done. Is there a way to find out what commands are hidden behind the right arrows that precede the results shown? For example: If my worksheet shows x^2 -> 2x, is there a way for me to have Maple produce x^2; diff(x^2,x); (or similar) which shows I took the derivative of the expression with respect to x. Thanks in advance. Tom

I was surprised to find MAPLE doesn't see to have the Kronecker delta as a system function. It was simple enough to write one, but that brings up a question. What if you have certain simple functions which you want to have always available, even after a restart. If you do restarts alot, it can become tedious to keep having to go back to the execution group in which they are defined and click on it. Is there any way to define a function as 'Permanent'. I'm just starting to read about modules. Is the use of modules a recommended way to have user defined procedures stay in the system af

Download 569_ODE-25 Reactions.doc Hi, I want to solve 25 set of differential equation for unknown variable and contants. Problem Statement: Solve the following set of differential equations for concentrations terms in terms of CA0 and t CA, CB, CC, CD, CE, CF, CG, CH, CI, CJ, CK, CL, CM, CN, CP are the variables and k1 to k25 and CAO are constants Initial Values: t=0 CA=CA0 and CB=CC=CD=CE=CF=CG=CH=CI=CJ=CK=CL=CM=CN=CP =0 How do I proceed for the same?

Hi,

The two functions, they were cut off in the original post, are:

f:=sin(3*t) (0 < t < Pi)

and the second function is:

f:=cos(Pi*t) (1 < t < 4)

Set up using unit step functions and graph the functions.
Function is 0 outside the given interval.

I have searched the Net, Application Center and Maple(10) manuals and am stuck as to how to write these solution with Maple(10) Commands.

Any help/tips will be greatly appreciated.

TIA

Given the following information: f:=sin(3*(t)) (0 <><><>

I am currently working on a project with Maple, and I am stumped beyond belief. The first I have been working on for something like two weeks now. I have worked on it with the university computers, and my own computer and recieved the exact same error. I don't see any syntax errors, and apparently the TA has been able to get his to work. So could someone possibly point out my stupid mistake? f1:= (2*x(c-Pi/2))/sqrt(1-sin(c)); fint:= int(f1, x=0..1); limit(fint,c=(Pi/2), right); And it outputs the following: signum(int(2*x(0)*sqrt(2), x = 0 .. 1))*infinity

Hi, Does the 'restart' command clear all the packages that have previously been loaded? example: with(package1): with(package2): " " " Maple commands and general problem solutions Then in the same worksheet following the previous work restart Do I have to reload the packages or does Maple just reset the variables used to null? tia Larry Ciak
