Hello Grant,

Thank you for using MaplePrimes.

Unfortunately, I believe the question you are asking is a bit above the level of this public forum. This question will probably require some input and back and forth with the T.A. developers. Might I suggest you contact Maplesoft Technical Support directly at so that we can look into your issue through the proper internal channels?

We look forward to hearing from you,

Hello Elisabeth,

Thank you for using MaplePrimes. I have investigated your claims and can reproduce them. It seems that once you advance to a new "Adaptive Question" section, and then click "Verify" to check the current section's result, the previous section's selection disappears.

I have reported this to our T.A. Developers so that they can address this in a future update release of our product.

Thank you for bringing this to our attention. In the future, if you think you have encountered a bug or usability issue, please do not hesitate to reach out to Maplesoft Technical Support directly by emailing

Thank you for using MaplePrimes. I have already answered this question for you in email form (in response to an email you sent our department), but thought that users on MaplePrimes may benefit from this answer as well.

 I think that to better acquaint yourself with the differences of Worksheet and Document mode, you should refer to this help page:

 Some key points that will help you are:

  • When you are in a Worksheet block, you can press F5 to switch between 1D and 2D input. If you want to get out of Worksheet mode entirely, you can click either:
    • Edit > Document Blocks > Create Document Block (creates a new document block below your current block). 
      • The symbol along the top bar that looks like a line between two triangles point at eachother (next to button "T" and ">_") will do the same thing.
    • If you highlight even a single character in a Worksheet Block and click the Document Block symbol along the top bar (explained above), you will instead convert the Worksheet Block to a Document Block.
      • This will still require you to convert the text to 2D math. To do so, highlight the 1D math text, right-click and press "Convert to > 2-D Math Input"
  • You can press "CTRL+Delete" to remove an existing block on your worksheet.

With these tips you should be able to get back on track. Additionally, you may find the following information about 2D math keyboard shortcuts helpful:

Hello again,


This time I have a full solution for you! To see two methods that will work for you, try the algorithm variables:

$numfmt=numfmt("#", $year);

Both will display the value without the comma. Use $year for your calculations, and $numfmt for your display variables. The Maple TA Built-In command numfmt() will work great for this application. 

The Maple command printf() will also work, but Maple calls in general are quite resource intensive. We tend to advise users to avoid Maple calls as much as possible for simple applications like this to keep their instance running smoothly. I have however included "printf()" here as sometimes it is the most convenient way to force values to appear as you would like. Keep "printf()" in mind moving forward.

As always, feel free to keep using MaplePrimes or email Maplesoft Technical Support directly at for technical help with Maple T.A.

Hope this helps. Let me know if you run into any snags.

Thank you for using MaplePrimes, and MapleSim. There are no silly questions here!

It looks like you are well on your way with using our software. While I cannot speak to the exact specifics of this model and its content, I can certainly help you interpret the model and make the changes you are looking for.

When you first open the worksheet, click the red rectangular prism in the "Nacelle Visualization" section and change the colour of it in the "Properties Pane" on the right of the MapleSim GUI. In the tower section, click the red vertical cylinder (name= CG1) and change its colour as well. CG1 represents the shape used for the tower of the turbine, and the nacelle is the electronics housing at the top of the tower.

In the "Rotor" section, the leftmost CAD item (name= HUB) is the connection between the rotor blades and the nacelle box. You can change the colour of this as well if you wish for our visualization. The remaining 3 CAD items are the blades themselves. Change the colours if you wish for visualization. Now let's run the simulation by clicking the "Play" button up at the top.

With the new colours, it should be more obvious what each component represents. For further insight into the model, if you click the "3-D Workspace" button to the left of the "Analysis Window", you will be presented with a display that can really help you orient yourself (in Maple 2016 this button is 3 cubes stacked triangularly). Now if you click any object in your model worksheet, it will be highlighted in the 3D workspace. If you click the "Show/hide attached shapes" button in the 3-D Workspace (Maple 2016 has this as a square circle and triangle image), you can hide the shapes and CAD components which conceal the inner workings of our model. The shapes are for visualization purposes and do not affect the model.

Now that we have a clearer understanding of the model, if you click on the RB2, RB3, or RB4 body components at the end of each rotor blade (in the worksheet, this looks like a circle with a checkered pattern in the middle), you can change the "[I]" inertia matrix in the worksheet's "Properties Pane" to reflect the inertia you would like each component to exhibit.

If you are still having trouble navigating MapleSim, there are plenty of resources you can use to get more comfortable with our software including:

  1. Product tutorials in the MapleSim Help > Tutorials section.
  2. Videos on our Maplesoft Youtube Channel
  3. Exploring some simple example models in MapleSim.

I hope this helps clarify some of the issues you were having. If you have any technical questions, feel free to continue using MaplePrimes, or directly contact Maplesoft Technical Support at


Best Wishes,

Hello again!

Glad to see you are moving along and getting more indepth with Maple T.A.


For this question I can show you a common grading tool that we recommend. It involves the Maple command "InertForm:-Parse()". Running the command: "InertForm:-Parse("4/16")", in Maple will return the value: "`%/`(4, 16)". As you can see, it pulls out the division operator (with the leading % sign), and retains the values entered by the user.

This works the same for Maple T.A!


Designing a simple question for you:



Question goal: "Enter in the reduced form of $A/$B."

Maple Graded with Maple Syntax Answer Box (symbolic or text based):

     Answer : $A/$B

     Grading Code: evalb(InertForm:-Parse("$ANSWER")-InertForm:-Parse("$RESPONSE") = 0)

If you attempt this you will notice that $A/$B will be reduced, as being cast to the variable $ANSWER operates on it and reduces it. Meanwhile, $RESPONSE is immediately "Parsed" from its "Inert Form", so is not reduced. Only the $RESPONSE "1/4" will be marked as correct. If you replaced $ANSWER in the grading code with $A/$B, the only correct answer would be "4/16".

This also work for whole numbers as well; with $A=4,$B=4, 1 is the only accepted response. You can play around with conditional statements if you would like the option 1/1 accepted, or add a line explaining to the users that whole numbers should be written a specific way.


Please let me know if I can help clarify anything I mentioned above or provide some additional support.

Thank you for joining our community here at MaplePrimes. For complicated solutions like this, where multiple types of answers should be accepted, we can usually direct a user to use our "Maple Graded" question type, which accepts "Maple Syntax". This special syntax makes calls to our comprehensive Maple codebase which can help when designing complicated questions.

Unfortunately, in this case, the current design of Maple Graded questions is such that an empty response (No answer) is always graded as incorrect.

If you have further questions about this topic, or if you would like to have a bug looked at or addressed, please contact Maplesoft Technical Support directly by emailing

Best wishes,

Hello, and thank you for using MaplePrimes.

Unfortunately the functionality you are looking for is not available in the current release of Maple T.A. 10, and so will not be available with your product, Maple T.A. 8. While I cannot comment on whether our developers will include this in later releases, it may be something they consider!

While in no way an equivalent option, we do currently support matching-type questions that utilize a dropdown box to select matches from a list of options. A complete list of question types can be found here.

I believe you may be specifically interested in Maple T.A. 10's Math App type questions. Math apps are specially designed questions that utilize Maple Worksheets to provide a more robust and rich toolkit for developing questions to evaluate students.

Maple T.A. 10 also has the ability to share Math App questions over the MapleCloud.

To view some examples which demonstrate the power of Math Apps, feel free to visit the MapleCloud Math App center. Some of these Math Apps could potentially be turned into Math App Questions as you'd see them within T.A. with the addition of some simple grading code to the Worksheet, the same way you would mark a question in T.A.

I hope this clarifies some details. If you would like further support or consultation in setting up new questions or Math Apps, do not hesitate to contact Maplesoft Technical Support at , or continue using MaplePrimes.
