## How can I simplify the way I write simplification ...

I'm creating a randomly generated question bank that generates the following STYLE or problem:

12x-4y2
3x6y-5

I'm currently trying to use the answer type "formula without simplification," as I'd like to avoid the students putting the questions in as the answer, and this has been driving me crazy for hours now.

I have tried the "maple" function to simplify. E.g.:

\$ANS = maple("( \$C1*( \$V1^\$A1 )*( \$V2^\$B1 ) ) / ( \$C2*( \$V1^\$A2 )*( \$V2^\$B2 ) )");

But it always throws an error.

I have simply done the math in the algorithm section, so you end up with an answer variable like this:

\$ANS = -4.0*(((z)^2.0)/(5.0*((p)^9.0)))

However, it will still count all answers submitted as incorrect.

Any help would be GREATLY appreciated =/.

Variable name clarification
I have \$C1 and \$C2, which are the constants of the numerator and denominator, respectively ("12" and "3" in the example).
I have \$V1 and \$V2 which are the first and second variable, respectively, (in the example, "x" and "y").
I have \$A1 and \$A2, which are the exponents for the variable \$V1 in the numerator and denominator, respectively.
I have \$B1 and \$B2, which are the exponents for the variable \$V2 in the numerator and denominator, respectively.

All these generate from some interesting conditions to create the problems I want (no variables named i, e, or o, for example,) but all properly initialize.

## Summary of the 2016 Maple T.A. and Möbius User...

by: Maple T.A.

From October 19-21, the third installment of the Maple T.A. and Möbius User Summit took place. Making the move back to Europe this year, the three-day conference was held at the beautiful Vienna University of Technology in the heart of Vienna, Austria. The scope of this year’s event expanded to include Maplesoft’s newest product, Möbius, an online courseware environment, which is designed to help academic institutions move their STEM courses online.

This year’s Summit brought together participants from 20 countries, including Australia, the Czech Republic, Poland, China, Norway, India, Egypt, Japan, the Netherlands, and many others. Needless to say, there is great interest in learning more about how Maple T.A. and Möbius can play a role in shaping the educational landscape.

Video recordings of each presentation will be made public soon, so keep an eye out for them!

Getting Down to Business

Presentations were divided into 5 overarching themes as they relate to Maple T.A. and Möbius: Shaping Curriculum; Content Creation; Experiences Using Möbius; Integrating with your Technology; and The Future of Online Education. Presentations were given by representatives from schools across Europe, including DTU (Denmark), TH Köln (Germany), Imperial College of London and University of Birmingham (UK), Vienna UT (Austria), KTH Royal Institute of Technology (Sweden), Université de Lausanne (Switzerland), and others.

Many talks showcased the impressive versatility of Maple T.A. as a online assessment system, and Möbius to have practical applications in all STEM subjects, from Nuclear Engineering to Operations Management and many subjects in between.

Perhaps the discussion that gave Maplesoft the most feedback was led by Steve Furino from the University of Waterloo, who divided attendees up into groups to formulate a wish list of what they’d like to see in a courseware authoring environment. The list had over 40 items.

Notable Quotables

Many thought-provoking statements and questions were posed, but the following few stood out above the rest:

• “Wouldn’t it be wonderful if you could take the best course from the best instructor anywhere in the world?”
• “With Maple T.A., we can divert resources away from grading and over to tutoring.”
• “Möbius rescued us!”

Get the party started!

While each day was full of invigorating conference discussions, evenings provided ample opportunity to ditch the suit jacket and tie, and enjoy the lively Austrian atmosphere. The first evening at the Zwölf Apostelkeller was the perfect venue to break the ice while satisfying those taste buds longing for some traditional Viennese cuisine. Once Schnitzel, Käsespätzle (a delicious German version of Mac and Cheese), Strudel, Kaiserschmarren (shredded pancake), and a glass or two of wine hit the table, people soon forgot about the pouring rain outside.

It would have been hard to top the social in the Apostelkeller, but the next evening sure tried.

Day 2 finished with an impressive formal dining experience at the historic Gerstner Beletage in the Palace Todesco, built in 1864 and situated directly across from the Vienna State Opera House. The 500-room palace was home to Eduard Freiherr von Todesco, a well-known Viennese banker.

The skies finally cleared enough to take some photos, but only after most people had gone home. Thankfully Aron Pasieka, Möbius Project Manager, was still around to get some great shots of the city. Enjoy!

From beginning to end, the entire Summit was very well received by everyone who attended.

We would be remiss if we did not thank our incredible hosts at the Vienna University of Technology. Stefanie Winkler, Professor Andreas Körner, and Professor Felix Breitenecker were beyond helpful in bringing many of the finer details together, as well as helping many people overcome the language barrier.

We can’t wait to do it all again in London, England in 2017, and hope to see just as many new faces as familiar ones.

## Maple T.A. in Japanese?...

I need to do assignments on Maple T.A. but the website is in Japanese?

Everytime I visit (doesn't matter whether I type in the webadress or whether I follow a link via Google or elsewhere) saxion.mapleta.com/saxion I get a website that's entirely in Japanese.

My PC language is English (UK) and Dutch, I have tried removing cookies, history etc of my webbrowser. Nothing has helped. I can reach the English site via my mobile phone browser.

## Hiding assignements in Maple TA...

I have a base class with a lot of assignements. The classes that I let my students use are all child classes of that. I used to be able to hide all the assignements except those, that the students should actually work on, but now I can no longer do that. The base class is shared with several colleges and not "owned" by me, but that didn't ust to be an issue. Is there a solution to this problem?

## Syntax error: Token[gte]...

I am getting the following error in one question

Error handling the file: /usr/local/hosted_apps/MapleTA/11/webapps/mapleta-2016.0.3-1148820/WEB-INF/modules/proctoredTest/questionSheet.html

Does anyone have any idea what the problem could be? Link to question file:questions.qu

## Angle larger as 180 degrees...

For a question for my students I want them to calculate tge resulting vector from two vectors. The student had to answer by giving the length and angle of the resulting vector.

For the question the vector angle is always larger as 180 derges, the student should for example give a result of 270 degrees.

Currently I'm using the following code:

\$F1=100;#range(200,500,20);
\$F2=100;#range(100,200,10);
\$A1=45;#range(10,80,5);
\$A2=45;#range(10,80,5);
\$A1r=180+\$A1;
\$A2r=360-\$A2;
\$F1x=maple("cos((\$A1r)*Pi/180)*\$F1");
\$F1y=maple("sin((\$A1r)*Pi/180)*\$F1");
\$F2x=maple("cos((\$A2r)*Pi/180)*\$F2");
\$F2y=maple("sin((\$A2r)*Pi/180)*\$F2");
\$V1=maple("Vector(2,[(\$F1x),(\$F1y)])");
\$V2=maple("Vector(2,[(\$F2x),(\$F2y)])");
\$V3=maple("(\$V1)+(\$V2)");
\$F3=maple("LinearAlgebra[Norm](\$V3)");
\$V0x=maple("Vector(2,[1,0])");
\$A3=maple("LinearAlgebra[VectorAngle]((\$V0x),(\$V3))");
\$A4=maple("evalf(((\$A3)*180/(Pi)))");

As you can see maple will always give an angle smaller than 180 degrees since the angle between two vectors is always 180 degrees or smaller.

Can anyone tell me how I should code this problem such that the rest for A4 will be 270 degrees rather than 90 degrees, as is given from the current way of coding.

Thank you in advance.

## Maple T.A. course materials – Engineering Mechanics...

by: Maple T.A.

Hanze University of Applied Sciences Groningen has created 105 questions related to engineering mechanics for structures (statics/construction). These 105 randomised questions with graphics are used for first year students in civil engineering, structural engineering, architectural engineering and building engineering.

The topics of the course modules are as follows:
- Force Vectors (10)
- Support Reactions (26)
- Internal Forces (31)
- Stress (21)
- Trusses (17)

All questions have a translation button which makes it easy to switch from English to any other language. The questions are first shown in Dutch [NL] but by clicking [UK] in the Preview, the English version is shown. The text can easily be edited and changed into the language of choice in the Maple T.A. question editor. Only the button needs adjustment in the question source.

60 questions are “exercises“ which means that these questions have extended feedback. The remaining questions (45) are “tests” meaning that the questions include no feedback.

## Maple TA 2016: Lists depopulate in adaptive questi...

I am currently working on an adaptive question in Maple TA 2016 and it seems that there is a bug in the drop - down list functionality:

After I click "Verify" in a section, the answer disappears even though I choose it to be displayed. The window simply goes back to showing (Click for List) instead of keeping the answer, see the screenshot below.

Perhaps I am doing something wrong, though I have used Lists extensively in the previous version and never had that problem ..

Thanks for your  help!

## Formatting output of variables in Maple TA...

I apologize, as I'm still very new. I've flipped through a lot of pages, but I'm unsure of how Maple code translates to Maple TA.

I have randomly assigned an integer for the value of a year in Maple TA. I'd like it to appear as "2013" for example, but it will instead appear as "2,013". Is there a way to set the output formatting of a variable individually within a problem in TA?

Thanks!

## Problem with frac() in MapleTA ...

I am setting up a practice set on how to find a common denominator, add, and reduce.

If I do not set "allow arithmatic", there is no way for students to correctly type in the answer, which is CURRENTLY the return value for a frac() function call. If I DO set "allow arithmatic", the student can just literally type the question into the answer box to get full credit / never has to reduce, etc, which defeats the purpose of the lesson. This is also the case with the Maple Graded answer type unless I do something fancier than I'm doing.

I can set up the answer properly without using frac() and reduce the fraction, but then--when the answer should be a whole number--the student has to type in "3/1" as an example.

I've also tried setting up an if statement for the answer, but when i convert the numbers to strings, then "2/3" becomes .2.0/3.0".

So, at this point, I'm super open to ideas.

# Define the denominators. We want them to be between 2 and 8.
\$B=rint(2,8);
\$D=rint(2,8);

# Make it so that the numerators can be between 1 and 1 less than the denominators.
# We also want to make sure they're not 0.
# Hashtag dividingby0.
\$R=rint(-\$B+1,\$B-1);
\$A=if(\$R,\$R,1);
\$S=rint(-\$D+1,\$D-1);
\$C=if(\$S,\$S,1);

# Calculate the numerator multiplied by the denominator. We'll do this step expressly
# because we'll want it for our feedback.
\$X=(\$A*\$C);
\$Y=(\$B*\$D);

#Calculate the greatest common factor and the answer.
\$G=if(gcd(\$X,\$Y),gcd(\$X,\$Y),1);
\$ANS=frac(\$X,\$Y);

## When the correct answer is no answer...

Greetings, all!

I'm extremely new to Maple T.A., and I am building tools for my math department since I'm the only one with a programming background. I have a generic question, and sincerely apologize if I've missed it being answered elsewhere. It's a case that will probably come up multiple times for us, so I was hoping to find an answer =).

I have a problem where students are adding exponents of like bases. As an example, you get questions that look like this.

When the coefficient is 1, I'd like to accept a blank answer in the first response area as a correct solution. Is there an easy (or less easy =) way of making this happen?

## Cell padding in tables does not work...

Hi All,

I seem to have problems with the table formatting in Maple TA 2016, concretely changing the cell padding has no effect. Is this a general issue ? I don't have this problem in Maple TA 10 (I tried both versions using the same browser (Safari)).

Thanks!
