Hi Rex, I see that Purdue has a guide on Entering Math Expressions in LON-CAPA at https://www.math.purdue.edu/academic/files/courses/2016summer/MA16010/EnteringMathExpressionsinLON-CAPA.pdf
While it is possible to author questions in LON-CAPA that accept this syntax, I do not believe that this is strict Maxima syntax: Infinity is written as inf Negative infinity is written as minf (though I think -inf will still work) The constant pi is written %pi The exponential function is written as %e^(x) or exp(x) 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. ln(x) is otherwise interpreted as l*n*x which makes accepting equivalent answers difficult.
