<p>I was just wondering about whether there is (or should be) a
"standardized" way to do it. I have decided that what I will do
is use a formula response with preprocessing to make student
responses case-insensitive.</p>

<div>I see that Purdue has a guide on Entering Math

<div>While it is possible to author questions in LON-CAPA that
accept this syntax, I do not believe that this is strict
Maxima syntax:</div>
<div><br>
</div>
<div>Infinity is written as inf</div>
<div>Negative infinity is written as minf (though I think -inf
will still work)</div>
<div>The constant pi is written %pi</div>
<div>The exponential function is written as %e^(x) or exp(x)</div>
<div><br>
</div>
<div>ln(x) is written as log(x) - this is confusing to
students but you could write a mathresponse problem to
redefine ln(x) to be log(x) in the answer algorithm if you
want.</div>
<div>ln(x) is otherwise interpreted as l*n*x which makes
accepting equivalent answers difficult.</div>
<div><br>

<div>Best,</div>

I am developing some <formularesponse> questions for
Calculus I limits<br>
at infinity. Sometimes the answer is +infinity or
-infinity, sometimes<br>
a constant (horizontal asymptote). If I set the correct
response as<br>
"inf" (lowercase), the previewer correctly interprets the
symbol as<br>
expected. A guide published by Purdue suggests that all
caps should be<br>
used, "INF." I had the answer in a question set as "-inf"
and a student<br>
entered "-INF" and it was marked incorrect, as Maxima
should, because<br>
uppercase and lowercase symbols are different to Maxima.<br>
<br>
I guess I am just looking for clarification on a standard
way to do this<br>
in LC, given the behavior of the javascript previewer.<br>
