Maybe someone else here knows the answer, but if your question is about Maple worksheets then I'd also suggest contacting the Maplesoft support team directly at https://www.maplesoft.com/supp...

Or alternatively, the Maple-specific community MaplePrimes may know the answer. They are located at https://www.mapleprimes.com/

The 40px spacing applies to the iframe for the entire HTML question. Whilst your trick worked for me, I'd suggest moving all of your Question Text to inside the Question HTML: part of the response area:

I think Maple is attempting to simplify the expression. Changing $VP1="(sqrt(6)/6)*(L^3*S/E)^(1/4)"; should help, but still sqrt(3)/6 is shown as 1/6*sqrt(3)

You cannot use the Equation Editor in this case?

I have been able to search for content in the Cloud in Maple T.A. 2017 - e.g. searching for Distribution gives any folder with 'Distribution' in the title, as well as questions containing 'Distribution' in either the title or the question text. Can also use * to search the start of words e.g. searching Geom* will give you results for Geometry and Geometric. However I'm afraid I don't see the Fourier series folders you are referring to (either in the list or by searching).

EDIT: Also if you are looking for a specific topic, try the "Subjects" list under Maple Cloud, instead of "All Content Types".

Hello dnucinkis,

I'm afraid I'm not observing this problem, it sounds like a problem specific to your service. Can you please report this to help@maplesoft.com along with the URL you are using to access Maple T.A.?

You will need to make sure that you are using the Maple-graded response area with Maple Syntax on. From there, the grading code depends on how you expect students to enter their response.

Part 1) Text Entry: I assume that you have a working variable $v for the LinearAlgebra[RandomVector] command. If students enter [1,2,3] then use the grading code 

u:=Vector($RESPONSE); evalb($v.u=0);

Part 1) Symbolic Entry: Similarly, where $v is the random vector, the student uses the Matrix/Vector entry button, then use the grading code

u:=convert($RESPONSE,Vector); evalb($v.u=0);

For 2), you just need to test that the two vectors in the basis are orthogonal and both satisfy the equation of the plane, correct? Suppose $plane represents the equation of the plane without z (e.g. $plane=3x+2y). In Symbolic mode, if the student enters both vectors separated by a comma, then try this:

r:={$RESPONSE}; evalb(eval($plane, [x = r[1][1], y = r[1][2]]) = r[1][3] and eval($plane, [x = r[2][1], y = r[2][2]]) = r[2][3] and u.v = 0);

If this does not help solve the issue, I would suggest exporting the question as you have designed it currently, and attaching the zip file here.

For comparing two sets, I would usually suggest something more like 

evalb(rep=$REP); 

instead of the default code. However in this case, Maple doesn't always try to equate an exact number (i.e. fraction) with a floating point number unless you force it to.

Therefore, instead of the evalb line, try this line to force direct comparison between each set element:  

is(rep[1] = $REP[1]) and is(rep[2] = $REP[2]);

It depends on the whole question - you would need to be able to change how $VP1 is written. 

Can you please provide the full algorithm code?

Assuming that you are using a Maple-graded response area with Text entry only (which appears to be the case from the screenshot), what do you have entered for the "correct answer" and "grading code"?

@Metahofzicht I'd suggest making sure the Algorithm preview runs, and then change the grading code back. The quotes are required in order for Maple to recognize $RESPONSE and $TA as strings:

resp:="$RESPONSE";
ans:="$TA";
evalb(parse(StringTools:-LowerCase(resp)) = parse(StringTools:-LowerCase(ans)));

Also, in T.A. 2017 you should be fine with Pi in either Text or Symbolic mode - if Symbolic mode isn't working for you ask help@maplesoft.com
