I'm just writing a question bank for some simple integration exercises. This causes some problems with the constants of integration and the syntax of maple graded questions:
If I ask for
int(1/sqrt(x^2+4),x) one student could give the correct answer
ln(x+sqrt(x^2+4)) and another one could give
arcsinh(x/2), which is correct as well but with another additive constant. In formula mode one of these results would not be acknowledged as correct.
Therefore I tried to use maple graded questions and compare the differentiated results.
I used the syntax like in the manual at http://www.brownstone.net/support/edu/authoring/index.html
but with latex2ta.mapleserver.com the \maple-part translates to
qu.1.1.part.1.maple=evalb($RESPONSE = evalb(simplify(diff($RESPONSE,x)-$b)=0););@
which gives a false result. If I change the question bank by hand to
it works fine.
Did I make a mistake in my LaTeX file or is this a mistake in latex2ta? Is there an easier way to accomplish what I want or do I really have to change all edu files by hand after translation with latex2ta?
Any help is welcome,
