@EntilzaV Sorry. I can't get this url to work. Could you try again please?

You should be able to drag a file into the editor window and it should then place a hyperlink to the file in the post. You may need to wait a few seconds if it is a large file. You could also try using https://www.file.io/ or equivalent service and pasting a link here.

Can you export the question and post it so I can see if I can replicate you issue?

Hi everyone in the Maple T.A. and Möbius Community. I want to kick off the inspiration section of the community with a great opportunity to learn from experts and other innovators in the Online Education space. With this in mind I am very pleased to announce that I’ll be presenting at the Maple T.A. and Möbius User Summit in London this September. It’ll be a great opportunity to get the community together – and a chance to meet directly with Maplesoft product teams and management.

 
Themes will include:
·        The Successful Delivery of Online Education
·        Best Practices for Digital Testing and Assessment
·        Creating Engaging and Interactive Online STEM Content
 
Full details are here: www.maplesoft.com/londonsummit
 
If you’re interested in attending let me know – I can provide community members with a discount for 35% off the registration fee.
 
There’s an Early Bird offer running till 30th June too, so if you book fast, you can benefit from both discounts.

Have you tried the built in Maple MathML generator? If you maple expression is stored in $expr then try this. 

$expr="sin(x)/x";
#exprD=maple("printf(MathML[ExportPresentation]($expr))");

Maple has a latex function that can generate latex from a maple expression. This feature can be very useful in Maple T.A..

To generate latex from your expression you can use the following code in your algorithm section.

$expr=maple("printf(latex(sin(x)/x^2, output = string))");

This results in

To use the latex in your question text you need to wrap it in the latex delimiters.

What is the differential of \( $expr \) ?

The result will be

@Metahofzicht I've added a few cases.

You should receive

• 1.0 for H[m]*sqrt(3)/4*a^2*L*rho or where sqrt(3)/4*a^2 has been replaced by A
• 0.5 if you answer H[m]*a^2*L*rho 0.5 if you answer H[m]*C*a^2*L*rho, where C is any constant (you could set this to give the grade 0.25)
• 0 otherwise

I used this algorithm, where I've defined the grading code. Note I have different cases for C=1 and C= any other constant. 

$TA = "H[m]*sqrt(3)/4*a^2*L*rho";
$TApartial1="H[m]*a^2*L*rho";
$subslist = "A=sqrt(3)/4*a^2";
#define grading code function
$gc=maple("
proc(TA,TApartial1,subslist,RESPONSE)
if evalb(simplify(algsubs(subslist,RESPONSE) = TA)) then  1.0;
elif evalb(simplify(algsubs(subslist,RESPONSE) = TApartial1)) then 0.5;
elif evalb(simplify(RESPONSE = 0)) then 0.0;
elif type(simplify(algsubs(subslist,RESPONSE)/TApartial1),constant) then 0.25;
else  0;
end if
;end proc;
");

And the I have used a Maple-graded question with Maple-syntax and the following grading code.

$gc($TA,$TApartial1,$subslist,$RESPONSE)

Here is the Maple T.A. question Partgradfactorexample2.zip

@Metahofzicht Is this for a different question? Is this another example of partial expression grading?

@Metahofzicht This code should work but depending on your use case you may need to tweak it a bit. Often the easiest way to think about grading code is through the unit tests. For example, here are the unit tests that I used to test this grading code. What ever code I write must give the correct grade for the all the unit tests.

Unit Tests

Teacher's Answer          Student's Answer               Expected Grade

k*rho/E*sqrt(2*L^2/S)    k*rho/E*sqrt(2*L^2/S)         1.0
k*rho/E*sqrt(2*L^2/S)    k*rho/E*sqrt(L^2/S)             0.5
k*rho/E*sqrt(2*L^2/S)    0                                          0

If you add some other cases to this list, we can further refine the grading code.

Hi @Metahofzicht. Here is a way to do this in Maple. I have attached a working version for Maple T.A..

fact:=k*rho/E;
TA:=fact*sqrt(2*L^2/S);
if TA = RESPONSE then  1.0;
elif algsubs(fact = 1,RESPONSE) <> RESPONSE then  0.5;
else  0;
end if
