I have Maple 2016 on Ubuntu 16.04.  I get an error message when attempting to plot with an x11 device, that means I have missing fonts.

I do not get this error message on Ubuntu14.04, so, I think the difference is in fonts installed.


> plot([sin(x),cos(x)],x=-Pi..Pi);
> Maple X driver failure:BadName (named color or font does not exist)Warning: Cannot convert string "-adobe-helvetica-bold-r-normal--14-*" to type FontStruct
Warning: Cannot convert string "-adobe-helvetica-medium-r-normal--14-*" to type FontStruct

I have xfonts-100dpi and xfonts-75dpi installed.

Any idea what fonts I need to fix this?

Maple Worksheet - Error

Failed to load the worksheet /maplenet/convert/ .


I adopted the approach suggested in an earlier post (

/questions/137320-Plotting-A-System-Of-Ode) for the known results,

but some part of curve is missing.

The output I got is

... is finance.dll missing in Maple16 (64 bit), as it was in Maple15 (64 bit), so you have to install the 32 bit version instead?

Is it possible to move the finance.dll-file from Maple16(32-bit) to Maple16(64-bit)?


i am successfully transforming a 2D plot, when doing the exact analog thing to a 3D plot i get the error message 

Error, (in t) invalid input: unknown uses a 3rd argument, z, which is missing


i have no idea what's going on, please advise.


i made a minimum example:

this works:

> restart:with(plots):with(plottools):
> norm2:=x->x[1]^2+x[2]^2:
> N:=[0,1]:
> phi:=(x,y)->N+2*([x,y]-N)/norm2([x,y]-N):

I ran an advanced search in the application center at maplesoft and I'm not sure that it works properly.

Under advanced search I left the search field blank and selected MapleV to find all applications submitted for MapleV.  The first thing that happens is that it comes up with applications rated for newer versions of Maple.  Then it asks to click here to search our archived Maple-related applications (prior to Maple 10).

So I do that but it only produces...

sorry for this funny question, but where is the "Print Preview" command, it is not under File menu anymore and the export to PDF function is also missing... What am I doing wrong?

>f:=x->(1/sqrt(1+x^3));  I typed this function into Maple, but I keep getting: Error, missing operator or ';'. I'm not sure what I'm missing!

Under the Recent tab where you select Your Contributions.  It does not show all my posts.  Why is that?

Specifically, one example, my post on Wordle is not shown when I select My Contributions.  The only way I can see it is if I use All posts.  Please fix.

I have just seen this old thread in the "Recent" list, and, as I remember it well and because of curiosity, I have looked at it again. By browsing it, I have noted that as it stands right now, it makes little sense. As I keep a local Primes 1 backup, I have compared both and got a new unpleasant surprise to be added to the list brought by Primes 2: many posts (ten or more) in this thread, by Jacques, Joe, mine, etc, are missing, and the order of some remaining posts is altered.
