I teach a Maple course in a computer lab. There are many problems with Maple crashes. I've had the autosave feature disabled, which seems to help some. I'm running Maple 10.04 (New GUI version, Network, Windows XP). Last year, I used Maple 9 Classic and it worked beautifully. Has anyone had a similar experience? Any suggestions for improving the stability of the program ?

Hi everybody! a few weeks ago I asked in this forum a question: http://www.mapleprimes.com/forum/partial-differetial-equation-heat First I have to say that is really nice how easliy it solves the problem. Now, I really need to see values in the solution (I mean, by given x and t). In addition, I want to create graphs of the temperture as a function of t (I mean to state x, and then to check the temperture as a function of t in this x). Only I know is to do graphs of the temp' as a function of x) How can I do all of those things? Thanks A LOT !!! RedFox (:

Hello all ... while I was in Japan, Paul Goossens filled in for me as guest host of MapleCast Episode 10. Special guest is Dr. Marvin Weinstein of the Stanford Linear Accelerator Center (SLAC). Paul also interviews yours truly while I try to recover from jet lag in Philadelphia. T4.

We have just launched a brand new version of MaplePrimes that has many new features, tweaks and a fresh new visual design. These features are focused on making the site as easy to use as possible. The site will be coming out of beta very soon and we would like to get as much feedback from users as possible. Please comment on this post with any comments that you have about the new version of the site.

New features for the site include:

• Maple Ranking - All users are rated based on how active they are on the site. You get points for every posting that you make to the site. The more points that a user has the higher their Maple Ranking.
• Maplesoft.com login - You can now log into the site using the same information that you use to log into Maplesoft.com. If you already have a MaplePrimes account you can continue to log in as you did before. If you have a Maplesoft.com account with the same e-mail address as your MaplePrimes account your accounts will be linked together.
• Redesigned file manager - All files automatically have their own page that makes it simple to paste the contents into a posting. Images are automatically resized and creating HTML versions of worksheets is easier.
• Toolbar added to entry boxes - Buttons now appear at the top of all entry areas on MaplePrimes. This makes it easy to enter HTML or Maple code. Quick links to the file manager are also provided.
• User profile images - Upload an image to your profile that will appear next to your name on all comments that you place on the site.
• Email pages - A link is now shown on the bottom of every post that lets you forward the post to an e-mail address. You can use this to share a post with a friend or colleague or save it for yourself.

A user's Maple Rank is a way to see how active they are on MaplePrimes. There are four rankings as seen in this table. New users have no Maple rank. You receive points for posting various items on MaplePrimes such as blog entries, forum posts and comments. The more points you have, the higher your Maple rank. This system is similar to the feedback system on eBay, however instead of the points being assigned by users, points come from using the site.

The table below shows the number of points that each user receives for each type of posting.

All entry boxes have a set of buttons shown above them. You can use these buttons to insert the HTML tags required for common formatting on MaplePrimes.

All MaplePrimes users can upload an image that will be displayed next to their name when they post anything to MaplePrimes. You can choose any image that you like, it could be a picture of yourself, your cat, your favorite math expression, whatever.

Images can be up to 85 pixels by 85 pixels. They must be in GIF, JPG, or PNG format.

To upload your picture, click on "my account" on the top left of the page. Then click "Edit". Scroll down until you see the "Picture" section. Click "Browse" and then locate and double click on your image. Scroll down to the bottom of the page and click "Submit". You will then see your image on your user information page.

All posts on MaplePrimes have a link on the bottom labeled "e-mail this". Clicking that link lets you send a link to the post off to an e-mail address. You can use this to send it to a friend or colleague or just e-mail it to yourself to save the link.

Convolution of Finite Discrete Signals Tutorial Convolution of two finite discrete signals is a topic discussed in the Signals and Systems course offered by any electrical engineering faculty. This tutorial was created using Maple 10 using Maple components and can be use as part of computer aided teaching material or as a guided interactive tutorial. This worksheet can also be deployed on the web by using MapleNet. [New Maple Applications]

I am currently attending high school, grade 11, and have purchased Maplesoft to asisst me with my math home work. I'm well aware that the aplications of Maplesoft far exceed my needs currently, but I hope to continue its use further through to unversity. My issue is to figure out how to change the markings / ticks along the x axis of a graph so that I can plot a function i.e. sin(x) and know where π/2 ,π, 3π/2, and 2π are located. This will help as I learn the process of the transformations of a function. Any ideas? Thanks.David

MaplePrimes will be unavailable from 1:00 EDT till about 3:00 EDT on Monday, September 25. We will be making some major updates to the site that will greatly improve almost all aspects of the site. Be sure to come back Monday afternoon to check out all of the changes, I'm sure that you will like them!

When I log in today, I end up as user "dotdotdot" who has been a member for "one week one day". What happened? [G. Edgar, actually a member for a lot longer than that]

I just posted this application to the Maple Application centre, and thought that MaplePrimes users may be interested in seeing it. The title is Convolution of Finite Discrete Signals Tutorial and is designed to be a tutorial for students in a Singals and System course. Here is a screenshot: You can give the worksheet a try on MapleNet or Download it and try it out on your computer.

I'm trying to write a procedure which will (among other things) create a list of plot strcuctures and display them. For example: testplot:=proc(n) local i,P; for i from 1 to n do P[i]:=plot(x,x=2*i..2*i+1); end do; plots[display]([seq(P[i],i=1..n)]); end proc; But this doesn't work; apparently the plot structures I'm trying to create in the "P[i]:=plot..." line are somehow invalid. How can I make this work? Thanks, Alasdair
