## copy-paste your code...

Ali, can you copy-paste your lines of code (in 1D Maple input format) or, if it's too big, upload a worksheet (green up-arrow from menu).

## no irritation...

@Markiyan Hirnyk  I was not irritated, merely reporting back about the bug.

## testing...

Another test, if this is posted properly it will have worked for me too, thanks bryon.

## testing...

If you can read this, then the problem is likely to have been solved for me too. But I'll do more testing and report back if problem persists. Thanks.

## sample code...

the mapleprimes site is currently buggy, following a recent update. You could try to copy-paste your code by editing your above message. Copy-pasting code is usually more useful and/or efficient than attaching an entire file. Make sure you copy-paste as 1-d Maple input text, rather than 2-d or image. If you can still be bothered that is...

## explanation?...

[I am able to post a reply today so I'm copying the text I had branched off]

Preben, would this be considered a limitation or a bug or is it expected behaviour?

you can sort of see the problem with this:

r := 2*arctanh((1+s)*tanh(x)/sqrt((1-s)*(1+s)))+ln((1/2)*arccosh(1/s)-x):

L := limit(r, x=a*arccosh(1/s)) assuming s>0 and s<1;

/ 2 2 \
|/ / /1\\\ / / /1\\\ |
||exp|a arccosh|-||| s + |exp|a arccosh|-||| - s - 1|
|\ \ \s/// \ \ \s/// |
2 arctanh|-----------------------------------------------------|
| / 2 \ (1/2) |
| |/ / /1\\\ | / 2 \ |
| ||exp|a arccosh|-||| + 1| \-s + 1/ |
\ \\ \ \s/// / /

/ /1\\
- ln(2) + ln|arccosh|-|| + ln(-2 a + 1)
\ \s//

Then consider what happens as a tends to 1/2.

(I think this shows that) The limit is broken down into two diverging components that end up confusing Maple.

## maple player...

> "A free Maple Player provides for an additional desktop option to consume Möbius content."

I would like to thank and congratulate Maplesoft for coming up with a free Maple Player. There has been demand for such a tool for a long time and it's great to know it's here.

I also think it's great that Maple has an app. I haven't tried it yet.

Edit 2: I have now tried the Maple player and I successfully read my worksheets in the player. I was also impressed by the ability to rotate 3D plots in the player. So far, no problem. As far as I can tell, the worksheets must be saved in executed form to be readable in the Player (this can mean large worksheets if you have multiple plots). I intend to use the Player right away to share simulations with my co-author. I am very impressed.

The download is huge, does it have to be so big? Edit 3: I understand that the executable has to be large to be able to read any Maple worksheet.

Could you put the Maple player on a torrent to ease download? Is that something users can do? Thanks!

Edit 1: How about a free Maple calculator? The Maple calculator is my favourite tool. I would love to be able to use it as a standalone, to carry it around on a usb stick. You could also make a web interface for it: something like this http://web2.0calc.com/. To make the Maple calculator available online would be a great ad for Maplesoft. I bet many people who own Maple are not even aware of the existence of the Maple calculator.

## on-screen versus plot export...

When I export the plot as postscript (with the default numpoints or with a large number), I get a nice, smooth plot, as smooth as Maple plots have ever been for me. I do see the effect shown by the OP on-screen and if I do a screen-capture then I do get a jagged plot. But exporting within Maple gives me a top quality plot. (Maple 15 32 bits, Windows7)

## copy-paste...

you need to copy-paste the code exactly as given:

1.

dt:=plottools:getdata(p):

should be

dt:=plottools:-getdata(p):

missing -

2.

L:=ListTools:-Flatten(select(type,[dt],Matrix)):

should be:

L:=ListTools:-Flatten(select~(type,[dt],Matrix)):

missing ~
