Maple T.A. Questions and Posts

These are Posts and Questions associated with the product, Maple T.A.

I am trying to design a question to test for divisibility

$n3=range(0,9,1); and students have to choose the next digit to make the number divisible by 4

if $n3 is even the students must input 0,4,8 to be true

if $n3 is odd the students must input 2 or 6 to be correct.


I am not sure how to us the if(a,b,c) in this case or if I should be using indexof....or both?  Any help would be appreciated. 

When creating questions with Question Designer, how can I include notes that are visible to instructors only? I don't want students to see certain info. Is it in the "information fields"?   

I just wanted to remind everyone that this quarter's Möbius App Challenge closes on March 31st.  The next prize to be awarded is an Xbox One Prize Pack.  Video games are supposed to be good for the brain, after all, so really, you owe it to yourself to enter.

To enter the contest, all you need to do is:

1) Create an interactive App in Maple

2) While in Maple, log-in to the MapleCloud through the MapleCloud palette.

3) Click on the Send Document to the Cloud button

4) Set the group to "Mobius@admin", then hit send.

The group is moderated, so it won't appear instantly, but once approved it will appear on the Möbius Project server, where people can interact with it through a web browser, in Maple, or download it for use with the free Maple Player.

Here are the full contest details and more information on creating and submitting Apps.

Good luck!


I came to know that Chrome no longer supports MathML. Will this be an issue with Maple T.A.9/9.5? Should I require my students to switch to Firefox instread? 


My first post here.

I want to create my own questions on Maple T.A.  and it seems to me the User Guide is my only reference. Are there quick tutorials out there that I can refer to? Webinars would be helpful too.  I want to eventually create questions with partial credits.

Thanks in advance.

Congratulations to Andriy Andrusyk, from the Institute for Condensed Matter Physics of the National Academy of Sciences of Ukraine, who won last quarter’s Möbius Challenge with his application Heat Equation.  Dr. Andrusyk won a DSLR Camera Prize Pack.

Remember that you have until Mar. 31 to enter your Möbius Apps for a chance to win the next prize, an Xbox One!   Visit Möbius App Challenge for full contest details.



I'm trying to create a small app for Maple Player to graph solids of revolution. When I run the app in the desktop version of Maple T.A it works, but when I move it into the Maple Player App it crashes. Any ideas?

Maplesoft is holding its first ever Virtual User Summit on Feb. 27.  You’ll be able to watch presentations by both Maplesoft and Maplesoft customers, ask questions, have discussions in the lounge with other attendees, and even enter a draw, all from the comfort of your own home or office.

Here’s the agenda.  We’ll release more detailed information on speakers and session times in the next couple of weeks.

For more information and to register:  Maplesoft Virtual User Conference

We're looking forward to seeing you there. (Well, "seeing you" :-))


Voting is open for the next individual prize to be awarded as part of the Möbius App Challenge.  The winner will receive a DSLR Camera Prize Pack! 

Here are the finalist Apps:

If you do not have the latest version of Java installed, released last week, you may have problems viewing these apps, as older versions of Java seem to be quietly disabling themselves.  I’ve attached a zip file of the finalist Apps in case it is helpful.

Note that, if you ever have any problems viewing Apps in your browser, or simply want to work offline, you can always download a Möbius App and view it in Maple or the free Maple Player. To download a Möbius App, follow the link to the App and then click on the Download button near the top left of the page.

You can vote for your favorite through our Facebook page or, if you’re not on Facebook, send an email with your vote to

And remember, we are now accepting entries for the next quarterly prize. You could win an Xbox One!  See the Möbuis App Challenge for details.

Voting closes Jan. 30.


Maplesoft is a long standing supporter of the Who Wants to Be a Mathematician contest for high school students. For years, we have donated Maple as prizes to winners of the national and regional contests.

This year, being the 25th anniversary of Maplesoft’s incorporation, the company decided to support several projects that encourage the use of math amongst high school students and young adults. We dedicated a bigger budget towards projects that would enable us to make a significant impact on students and impress upon them the need for math and science in their future careers.

One project we undertook this year is giving an extreme makeover to the Who Wants to Be a Mathematician contest! With Maplesoft as a “Technology Sponsor”, the contest that was administered on pen-and-paper moved to a digital format. We donated our testing and assessment tool, Maple T.A. to administer the tests online, making the software accessible to every student that participated. This meant the students took an online test, and were automatically and instantly graded using Maple T.A.

The 2013 competition is underway, and the results are extremely positive:

  • The number of students that participated in the contest doubled this year, with over 2000 students from over 150 schools participating.
  • The competition introduced a second level of tests, making the competition more rigorous. After the first elimination round, eligible contestants moved to a second round with questions of increased difficulty levels.
  • By avoiding much of the paper work and manual corrections, the organizers saw significant savings in time and money.

Custom test questions were created in Maple T.A., which were accessed by students from a server hosted by Maplesoft. The simple and easy to use interface of Maple T.A. enabled the students to take the test without spending time learning the tool. Maple T.A. supports the use of standard mathematical notation in both the question text and student responses. Maple T.A. also allows free-response questions, including questions that have more than one correct answer.

Who Wants to Be a Mathematician is a math contest for high school students, organized by the American Mathematical Society (AMS), as part of its Public Awareness Program. Ten students will be chosen for the semifinals and two will qualify for the finals to be held at the Joint Math Meetings in January 2014.

More information about the contest that is currently in progress can be found on the AMS website



If I wirite in an algorithm in MapleTA 9.5 the number 0, and later use it (for export to latex), it becomes negative, but not if I pass through Maple:



results in:

null 0
zero 0
nullstring -0
zerostring 0


Why, and what can be done without passing through Maple?




Congratulations to Eric Miles, a graduate teaching assistant at Colorado State University, for winning the second individual prize of The Möbius App Challenge! Eric will be receiving an iPad prize pack for his app Stretch and Translate Sin(x).

Maplesoft launched the Möbius App Challenge earlier this year to give Maplesoft community members the opportunity to get involved in the creation of Möbius Apps. This contest seeks to challenge users to create Math Apps using Maple, submit them to The Möbius Project website, then award the most useful, creative, and effective submissions. Finalists from the individual level challenge are chosen four times a year, so make sure to enter the next round of the challenge for your chance at a Maplesoft prize pack!

Hi there,

How can I get gridlines in my plots in Maple TA? Se eg. the source of the following question:

Thanks alot in advance!

mode=Multiple Choice@
name=Grafen for den afledede@
algorithm=$r = rint(3);
$f1 = rint(3);
$f2 = rint(3);
condition: ne($r,$f1);
condition: ne($r,$f2);
condition: ne($f1,$f2);
$rf = switch($r,x^2,cos(x),x);
$ff1 = switch($f1,x^2,cos(x),x);
$ff2 = switch($f2,x^2,cos(x),x);
$fm = mathml("$rf");
$opgaveplot = plotmaple("plot($rf,x=-10..10), plotdevice='gif', plotoptions='height=250,
$rplot=plotmaple("plot(diff($rf,x),x=-10..10), plotdevice='gif', plotoptions='height=250,
$fplot1=plotmaple("plot(diff($ff1,x),x=-10..10), plotdevice='gif', plotoptions='height=250,
$fplot2=plotmaple("plot(diff($ff2,x),x=-10..10), plotdevice='gif', plotoptions='height=250,
Betragt funktion f(x) = $fm og dens graf herunder.&nbsp;</p>
<p style="text-align: center; ">
<p style="text-align: center; ">
Angiv hvilken af følgende figurer repræsenterer grafen for funktionen?</p>
choice.4=Ingen af dem@
choice.5=Der er flere rigtige@

Hi When Im creating subjects and child subjects you would think it would be kept in alphabetic order. But no. It just becomes one big chaos after refreshing browser. What am I doing wrong? Btw what is the difference between subjects and groups inthe question repository? Thanks in advance, Henry
