Students do the craziest things. This was an interesting bug to run into. The following lines all cause Maple 11 to lose connection with its kernel:
```
solve( x-x = 0 );
solve( x-x = 1 );
solve( x-x = -1 );
```

Whereas, the following lines do *not* cause Maple 11 to lose connection with its kernel:
```
solve( 1=0 );
solve( x-x+1 = 0 );
solve( x-x-1 = 0 );
solve( x=x+1 );
solve( (x-x)^2 = 0 );
solve( x-x = x );
```

Evaluate:
lim [1/x * ( (a^x - 1) / (a-1) ) ] ^ 1/x
x->infinity
where a > 0 and a is not equal to 1

The latest MapleCast episode,

Can't Touch This, is now available on the Maplesoft website.
Stephanie Rozek (that's me) guest hosts as Tom Lee is out exploring new frontiers… Paul Goossens interviews a group from

Quanser about their control solutions for industry, education and research.

MaplePrimes couldn’t exist without the generous contributions of many talented users. They answer others’ questions and post their own valuable insights and experiences for the rest of us to benefit from. In many ways you are true mentors. The MaplePrimes editors would like to acknowledge their contributions and to encourage others to be inspired by their leadership. We will be awarding a series of prizes for exceptional and continued contributions to this site.

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.

Hello all ... FYI, our site master Will Spaetzel is getting married this weekend. Please join me in congratulating him and his new bride Laura-Lee on their new life together! Many happy wishes to you two! The bad news is, during his absence (for a couple of weeks), some technical issues with this site may be a bit slower in resolving. We have back-up editors for Will but Will has special talents that are hard to match. Thanks for your patience. Tom 4.

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

Earlier today, I was re-reading an old post when I was inspired. The post asked how one could use typesetting rules to make the call of a procedure typeset as a binary operation. The example used in the post was something along the lines of:
`myproc(a,b);`

**becomes** `a <symbol> b;`

Inspired by a response to that post, I started looking at the help page for the `define`

command and doing some testing in Maple. I was ready to make a reply to that post, when I stumbled upon a mind-boggling error. In the time it's taken me to track down that error (and run various errands), the original post has vanished from my view. Perhaps it still exists somewhere, but for the life of me, I cannot find it; therefore, I post to the next most appropriate place to describe and discuss this shortcoming: This blog.

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.

This is to inform you that we are now shipping the newest version of Maple T.A. – Maple T.A. 3.0.
Maple T.A. is an easy-to-use web-based system for creating tests and assignments, automatically assessing student responses and performance. It supports complex, free-form entry of mathematical equations and intelligent evaluation of responses, making it ideal for mathematics, science, or any course that requires mathematics.
The new edition – Maple T.A. 3.0 – comes with increased flexibility in content creation, an enhanced user interface and improved grading and assessment capabilities

Maplesoft has now posted the 11.01 update for users running Maple 11. You can download the update

here .
As the website mentions, this update includes improvements in the following areas:

- Differential Equations
- Maplets
- Physics Package updates
- Plot legends
- Vector Calculus

**
Who is entitled to Maple 11.01?**
Maple 11.01 is available to all users running Maple 11. If your Help>About Maple 11 dialog from the Standard Interface reads Maple 11.01, then you already have the update and no further action is required.

Could some one help me to plot this population balance equation ?

In this episode Tom Lee takes some time to chat with three students working at Maplesoft for the summer. Laura Bradbury and Elyot Grant are both students at the University of Waterloo, respectively studying Computational Mathematics and Computer Science/Mathematics. Zach Daly is a Mathematics major at the University of Guelph. They discuss their opinions and experiences of using Maple in the student paradigm, and offer ideas for other students just starting out with Maple. Eithne Murray joins Tom to discuss Maple’s offerings and resources for students, and as always the latest news is covered, including information on the release of Vista-compatible Maple.

Maplesoft has just announced that a Windows Vista version of Maple 11 is now available.
If you already own Maple 11, you may download the update for Vista at

www.maplesoft.com/vista
If you do not yet own Maple 11, you can either purchase a Boxed copy of download version of Maple 11 for Vista. The Vista version is available for download immediately, and boxed copies will contain the Windows Vista version of Maple at the end of the month.
