Maple 13, Mac OS 10.5.7 It seems that when choosing export from a menu (for example to export a graphic), I get as the default directory not "currentdir" (which the user can change) but "homedir" (which the user cannot change). True? Some rationale for this?

I just noticed that in Maple 12 (and 13) the Layout palette's subscripted atomic identifier entry had its hover-over tooltip changed. By hover-over I mean the text based tooltip that appears after a slight delay when the mouse point is allowed to hover over the entry.

In Maple 11 it showed as subliteral which, while perhaps to entirely clear to everyone, was at least accurate. It meant: the unique subscripted name.

For example, x-subscript-y, as a subliteral...

I have a passing acquaintance with Maple 12, and looked forward to Maple 13 to see what improvements there might be. I began by creating a document based on a style that I created in Maple 12. Maybe that gives rise to some of the questions highlighted in this document. Does anyone care to comment?

I was fully expecting to write Part 2 of my postcard from China when a life-changing event interrupted my creative processes. My son Eric is thirteen and is about to complete grade 8. Math is not exactly his strongest subject but I blame it all on the fact that he has not started algebra in any substantial way yet… where math starts and that arithmetic nonsense stops.  In classic Eric style, he informed me that he had a math test the very next day and he absolutely needed to have a scientific calculator. “How did you do your homework so far then?”, I naively asked … “I don’t know … I faked it”.  After a moment of disbelief, with a sprinkling of anger, all mixed with a hint of pride that he got a B in math while “faking” the calculations, we got in the car and headed off to Staples.

It wasn’t that long ago that people were thinking that personal rocket jetpacks would be a reasonable means of transportation.  Unfortunately, we’re still a bit of a ways off on that dream.  That being said, we can still do a lot of cool things with rockets.

Rockets find their origins in ancient China.  The availability of black powder to propel projectiles was a precursor to the development of the first solid rocket.  The discovery of black powder by Ninth Century Chinese alchemists led to experiments in the form of weapons such as rocket-propelled fire arrows.

If I enter an equation label (crtl-space-L) twice in a row with an operator and without any spaces, Maple shoves the second label in before the operator.

So if I want this (1)+(2) what I actually get is this (1)(2)+ looks like it's doing some commutative quantum wierdness haha sorry I just had to put that in there.

The following computation crashes Maple 11 (maplew):

> sqrt(5);
sqrt(5);                (1)

> (1) / ((1) + 1);

where (1) is a label.

I've found a small bug, it's more of an aesthetics issue.

A:=P*(1+r/100)^n;

P:=100;

r:=5;

evalf(A);

100. 1.050000000

 

No brackets around the 1.05.  Happens in classic version as well. 

 

I am currently using Maple to deconvolute gamma ray spectra, using Howards method of finite extent and non-negativity. Although this method does work well, I would like to try deconvoluting these spectra using the method of maximum entropy., Unfortunately however, I am having considerable difficulty in finding the necessary information, that would enable me to develope a worksheet to perform this task. As a result of this, I would to hear from anyone who has any experience of this method of deconvolution.

Maplesoft launched a new application center on its website on April 2, 2009. One objective of the update was to make it easier for visitors to find great content for both Maple and MapleSim. We wanted to make sure that all pages list the best applications first. While on many pages, including the home page, the MapleSim content page and the Tips & Techniques page, our editors can control the order of the applications, with almost 2000 applications, editors cannot rank all of the applications manually.

So I'm a bit behind on announcing this...but better late than never.  The recipient of the Maple Mentor Award for the first quarter is gulliet.

I apologize for my tardiness, but I will announce the next recipient on time next quarter.

Congratulations!

I miss some familiar features from the classicalö worksheet in the standard worksheet, especially things like "find/replace" in 2D-math expressions, undo for mathematical operations.

Maple 12 fails to factor this polynomial factor(x^8-8*x^7-20*x^6+232*x^5+126*x^4-2200*x^3-836*x^2+6776*x+4403); Because I knew the zeros +/-sqrt(2)+/-sqrt(3)+/-sqrt(6) I could factor it myself. One factor is x^4-22*x^2-48*x-23 Just what are the limitations of factor? I saw no hint on the help pages? At what degree does it start to fail? Surely it can handle degree 3 always--but I guess not 8. So where does it start to give up without warning (as above). Is there a built in test for irredicibility (since factor can not be used as one)?

It will be very convenient if the worksheet automatic jump to the position that the cursor is in the middle of the screen if you reach the bottom. It is very unconvenient now. If I execute some existing worksheet step by step and I reach the bottom I can only see the half of the input, or if there is a loop I only see the first line.
 

Sometimes I only want to see the plot with varying axes formation, for example with logarithmic scale. But I don't want to change the style really. So it will be nice if the style goes back to the old style if I click on "Cancel":

Click on the plot to "plot-axes-properties",
change something,
click: "Apply",
click: "Cancel"

=> everything is like before the changing
