To anyone: Will someone provide maple syntax to plot the following lines f(x), x=a, x=b from x=c..d where f(x) is an explicit function and x=a and x=b are vertical lines and the extend of the graph from x=c to x=d. This should give me the graph of the 3 equations from x=c to x=d. I tried implicitplot, graph it led me nowhere. Many thanks PV

Ten days playing with Maple has proven that skills in one system don't necessarily translate to another. I have encountered a number of frustrations which are not so much a problem with Maple as my inability to match the subtleties of the new system. Some of the issues I have encountered:

• periodic locking up of the interface in document mode (this may be due to something I am doing wrong)
• getting used to the maple syntax and command list (it is further than the syntax of Mathematica than I originally suspected yet similar enough to completely mess me up)
• occasional odd state like behavior (which is, again, probably due to my ignorance than a problem with Maple)

These are the notes of a new Maple user attempting to come up to speed in, what is for me, a new algebraic manipulation tool. I am looking at the tool not so much as an engine for solving problems as much as I am interested in using it as a tool for teaching advanced physics concepts to students in the secondary school arena. Right now I only seek to use it as an aid to building better presentations for the students as well as supplying a dynamic environment for solving problems for students in my class.

I am just a beginner to use Maple and now I have a second order linear equation with boundary conditions to solve. I want to get the numerical solutions and plot the solutions. However, I have tried many times, and still do not get the solution. So I want to ask for help. my eqaution is simple but just sort of long. y"(x)=4-8(1-2/r)(1/r**3+1/r**2), here r=43.48arctan(0.05x-1.23)+41.1, The input of my program in Maple is: restart; sol:=dsolve({diff(y(x),x$2)=((1-2/(43.48*arctan(0.05*x-1.23)+41.1))((43.48*arctan(0.05*x-1.23)+41.1)^(-3)+(43.48*arctan(0.05*x-1.23)+41.1)^(-2))*8-4)*y(x),y(-2)=-0.65,y(40)=-0.11},y(x),numeric);

How do I use Matrices to solve linear equations?

In response to a question about collecting symbolic powers of polynomials, I suggested a few lines of code that solved the particular problem. Following is a procedure that enhances the technique to mimic, to some degree, the abilities of Maple's collect procedure, which handles integral powers. This enhanced version can take a list of indeterminates. It also permits use of an optional third argument, func, that is applied to the collected coefficients of a power.

When u mean maple, is it maplestory the game??????????????????????

I'm using Windows XP prof. edt. and Maple 9.5 I installed Maple and it is running properly but there is an important problem with the user-interface of Maple ; For example, scroll bars,check boxes,sliders. . . can not be seen on the interface. Therefore, for instance in the "Options", I can not understand whether a checkbox is checked or not. (The most important part of the problem :( ) I've already installed Java VM (jre1.5.0_06) What should I do ?

For no reason other than curiosity, we have a new poll ...

hey please help me out in the programming part of rtc ds1307 with 8051.......... i want to initiate the sec on the register of rtc and i want to see the output on port1 . do i need to connect sda and scl to RXD and TXD of 8051.As i am connecting these lines to port 2 of 8051.please help me and i wnat the program in asm language. Anand

I used to have Maple 10.02 running on Fedora Core 4. I recently upgraded to Fedora Core 5, and 10.02 no longer runs (no error is given). I can't install Maple 10 off the CD or the downloaded 10.03.

Let A be an n by n (0,1)-matrix. How draw the graph of the adjacecy matrix A?

Do you think that it's possible for Maple to ever be free software? I
suppose I should emphasise that this is "free as in freedom",
regardless of whether Maplesoft decides to keep charging money for its
use or not. Me, I don't see it happening in the near future, but I
harbour hope that it could happen for the following reasons:

1) Other success stories of free software, such as the Firefox
browser.

2) Maple, unlike the other leading brand, was built in a purely
academic environment by a community of mathematicians and
scientists who understand the need for free and open collaboration
