Fraction solving problems

dberge — Tue, 08 May 2012 16:29:51 Z

Hi,

I'm trying to have students solve a simple fraction problem like $a - ($b + $c) / ($d - $e), where each letter is a programmed variable and where $d, $e and its difference do not give zero. The answer could be either a fraction, or an integer (if the fraction can be simplified). If I use the Maple-graded type of question, this is possible, but the student can also write the initial fraction problem and get a good mark for it ! ...

How to do simple linear regression in Maple T.A.?

sreid — Mon, 23 Apr 2012 18:01:43 Z

I decided to convert an old LR question to Maple 15 syntax and update my Maple T.A. questions. I have it working in Maple, but in MTA I get an error: "java.io.IOException: Maple computation error", I've eliminated lines until I found out the error is when I use Fit to solve for the equation. What am I doing wrong?

Thanks, Stephen

I define 8 x values, and calculate 8 y values with random residuals. Then I solve using least squares.

Change to 1-D math (math input) with command in initialisation file

Petra Heijnen — Mon, 30 Jan 2012 14:24:28 Z

I've made exam questions for students that they have to answer by doing some calculations in Maple.

I would like to let them copy the commands they used to a Maple TA text field.

However, the standard worksheet in our computer lab uses 2-D math. Copying this 2-D math to Maple TA works fine with "paste as plain text", but copying 1-D math also works with ctrl-v in Maple TA, which is more convenient for students under stress.

Since I am not allowed change...

Announcing Maple T.A. 8 and Maple T.A. MAA Placement Test Suite 8

eithne — Wed, 04 Jan 2012 19:01:01 Z

New versions of Maple T.A. and the Maple T.A. MAA Placement Test Suite are now available. Highlights include:

- Adaptive questions provide students another chance when they give an incorrect response. Knowing the student is having trouble, the question can be adapted to walk the student through the problem one step at a time, allow students to try a simpler version of the same question before retrying the original, or whatever the instructor feels is appropriate.

MAPLE TA TEST about floating-point arithmetic

JessicaLiu — Wed, 09 Nov 2011 12:50:46 Z

Consider a "toy system" of floating-point arithmetic where each floating-point numberis of the form
x = (-1)^s × (1 + m) × 2^e-σ:

The mantissa is a binary number such that
m = 0:m₁m₂m₃ (base 2) belongs to [0; 1)

and the exponent e is a binary integer such that
1 ≤ e = e₃e₂e₁e₀ (base 2) ≤ 14:

Each m

Multiple answers

Hi!

Can anyone help me to write code that validates an answer to a equation of the sort a*x^2=cx.

There will be two solutions to the given equation and I don't know how to write it so it takes in and separates the two answers from the student and validates them.

Best

Error in MapleGraded Code?

armstrongc — Thu, 27 Oct 2011 17:28:40 Z

This should be astonishingly simple as a MapleGraded question but it stubbornly refuses to agree with me. Everything is marked incorrect ... one wishes for some feedback from MapleTA as to what is going on.

Student enters a vector. The goal is to have the dot product with <5,3,1> to be whatever value is chosen for $p, which is in the $ANSWER field:

$m:=<5,3,1>;
$d:=LinearAlgebra:-DotProduct($m,$RESPONSE);
is(($d-$p)=0);

Editing MapleTA login page

armstrongc — Fri, 14 Oct 2011 13:39:44 Z

We have MapleTA installed on our own server and would like to edit the Login page so that students realize they are on OUR MapleTA page ... students are not particularly observant (no, really!) and often try to login at any MapleTA site they find on the internet. There is nothing in the UserGuide on editing either the Login or Class pages.

Thanks!

Maplesoft hosting of TA

Ian Jones — Mon, 11 Jul 2011 14:00:13 Z

Hello.

After using many versions of TA over many years on our own servers, we are considering paying for Maplesoft to host TA. Can anyone offer any experience of using TA hosted on Maplesoft servers? We can think of many good reasons to change but are there any downsides? Is remoteness a problem, speed of access? We have a fairly typical university central computing service dept.

I understand that the way the hosting system works is that more than one server...

Using Maple TA (Version 5) is just annoying to me

mich — Sat, 09 Apr 2011 18:00:49 Z

Hello,

I started using Maple TA to create some online exercises for students at a universtity of applied sciences in Germany. I proceeded in writing the exercises with the help of LaTeX. Here I would like to share some experiences in a kind of overview. For me there are 4 major fields of disaffection:

1. In general, the Maple TA rendering of math content is very poor. Look at the layout produced by LaTeX and you know what I mean.

2. The conversion of LaTeX files provided by Maple TA ...

The best of MaplePrimes

hirnyk — Mon, 04 Apr 2011 06:50:48 Z

The recent flow of spam into MaplePrimes gave an opportunity to recall some pages fallen out of our memory: interesting questions, deep answers, and rich in content posts. It suggested me the following idea which I would like to discuss with the MP members. Maybe, it would be reasonable to create a new heading "The best of MaplePrimes" in MaplePrimes. For example, every month experts choose a few candidates to be included in "The best of MP". Then the...

question handling in TA6

Ian Jones — Wed, 23 Mar 2011 17:03:12 Z

1.I have been using TA for some years but we have only recently moved from version 4 to version 6. In versions up to version 5, when a question was edited there was a two stage saving process ie. the question was saved and the question bank was saved. Only after these two saves did assignements containing the question reflect the edits in the question. I have an assignment which depends on a question in TA6 and I have edited saved the question. The assignment does not reflect...

Explain fmt string in numfmt(fmt, x) function

paul kates — Tue, 08 Mar 2011 19:42:34 Z

Please explain details of the fmt string in the mapleta function numfmt. The help page only says

Returns the value of x, formatted according to the template fmt.

For example,

numfmt("#.00", 20.9)

How do I obtain the clock time in MapleTA and/or Maple

Steven Bellenot — Fri, 04 Mar 2011 18:09:35 Z

I have a mapleTA question that blocks students from starting a mastery assignment until I tell them how to do the problem. But some students are gaming it but finding out the problem from an earlier section. I want to game back by making the answer change depending on the wall clock, that is the section they are in. To do so, I need a clock function to tell the time. Since I can call maple inside mapleTA, a maple solution will also work.
