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

server: efnet channel: #maple this channel is unaffiliated with maplesoft. It is new at the time of this posting so be patient if there is not much activity at first. I know a bit about maple and may be available to help people with it. If you have never used IRC before it is not difficult. You may want to read about it a little by googleing IRC. if you just want to connect I have posted instructions about connecting to this and other math related channels on IRC at this link: http://web.mac.com/luther_driggers/iWeb/SFUMSU/NEWS/50430B9A-5AAD-48DC-B53B-A5565C352F70.html

When I click the "blogs" tab at the top, I do not get a list of blogs, but only "Bratva's blog" (in Cyrillic). Needs a fix...

Just announced. Performance imnprovements for start-up and equation editor improvements are some of the improvements. Download 10.03 patch here. T4.
