## Maths question

by:
a bus travels 200 km at a constant speed. a car travelling 10 km/h faster than the bus, completes the same distance in 1 hour less than the bus. (1) how many hours does the bus take to travel the 200 km? (2) what is the speed of the car?

## 2nd Fick's law (pde solution)

by:
The following is the code for the 2nd Fick's law with initial/boundary conditions. Unfortunately this code does not show me the result required for next process. It would be useful for us to proceed this work. Thanks in advance.

## Another Maple-Linux Problem

by:
I hope someone can shed so light on the following: I upgraded to SuSE10.3 -32bit recently and everything seemed to go well. Maple 11.01 was installed and has worked fine until now. Today was the first time I tried to print a file and 'Lo and Behold. There is no print function at all! Whenever 'Print' or 'Page Setup' is clicked there is a brief moment of 'wait' cursor and then nothing happens. No dialog box, no warnings just silence. I did a search for similar issues on Google but came up empty. I've checked the CUPS config file for the Linux fix regarding Sockets, that made no difference, I checked the installation of CUPS and it seems fine, indeed, every other application prints fine. By the end of the day I resorted to reinstalling Maple and that didn't make any difference either. I'm at a loss. Anyone using SuSE and Maple 11.01 care to comment?

## CodeGeneration -- Some constants are not replaced...

by:
Hi, I have a small problem. I want to export code to Matlab. The code is mostly a long expression with some named constants. The constants are set to some values in Maple and in Maple only the x-variables are therefore unknown in the expression. However, in the exported code, some of the constants are not replaced by their values. Does someone have a clue what this depends on? Best regards Johan

## SuSE 10.3 bug

by:
Hi again, Long time, no post but thats not an indicator of not stopping by and reading nearly every day. Now I'm looking for some advice on a bug. I'm going to be sending this MapleSoft too but I thought perhaps someone here may have some insight to its solution. Thank, Tim Bug on SuSE 10.3 I'm unable to run Maple 11 with the Java interface since upgrading to SuSE 10.3 Here are the errors messages: tim@linux-g0yu:~/maple11/bin> ./xmaple java: xcb_xlib.c:52: xcb_xlib_unlock: Assertion `c->xlib.lock' failed. /home/tim/maple11/bin/maple: line 446: 1881 Aborted '/home/tim/maple11/jre.IBM_INTEL_LINUX/bin/java' -Xmx400m -cp '/home/tim/maple11/java/xercesImpl.jar:/home/tim/maple11/java/xmlParserAPIs.jar

## New Student Forum

by:
Hello all ... FYI, we will be creating new forums specifically for Q&A geared towards undergraduate students. Our goal is to have a section of the forums that are more suited to the kinds of issues that younger users who have neither the computing or math experience, may have. We'll be uploading the test groups this week and the forums should be live by the end of the week. We'll also do subsequent refinements in the autumn once Will gets back. Tom 4.

## ICCOPT II / MOPTA 07

by:
On Monday, Aug. 13, I will be at a big optimization conference at McMaster University in Hamilton, Ontario. It's the joint International Conference on Continuous Optimization (ICCOPT) and Modeling and Optimization: Theory and Applications (MOPTA) conference. I'll be running a session with three Maple-related talks given by Jan Bakus of Maplesoft, Andrew Curtis of the University of Western Ontario, and myself. If any of you are attending the conference (and I

## Finding a Minimal form for a boolean expression

by:
I have some background in computer science; which may help explain my interest in Maple. :) In my Computer Science studies; one thing we were required to do was to minimize boolean expressions. I found this to be extremely tedious; something that you really want the computer to do for you. At least; that is how I saw it. So, I always thought that I would write a program to do; what we were doing manually. The result is the following application: Minimize Boolean Expression Worksheet

## Plotting Large Sparse Matrices in Maple

by: Maple

When working with large sparse linear systems you often want to look at their non-zero structure, however Maple's existing tools are all designed for dense matrices. I wrote a little tool to produce images like this in reasonable time. You can download the code here, and the rest of this post is a quick tutorial on how to use the included command. Maple 11 is required.

by:
The MapleReader has been the source of a bit of confusion on MaplePrimes lately. Hopefully with this post, we can help clear up some of the questions that have come up about it. The MapleReader is, as Scott03 mentioned in his response during a separate thread, an extension of Maple 11 that allows an eBook file format called an 'mbook' to be read. A number of authors are currently in the process of converting their content to an mbook file format, to be distributed independently of Maple. The reason why it was included in Maple 11.01 is to allow our authors access to it and it's updates for authoring purposes.
