This document plans to document features that the current symbolic response
|
|
supports. In general it allows the input and validation of math expressions,
|
|
up to commutativity and some identities.

Features

|
|
|
|
This is a partial list of features, to be revised as we go along:
|
|
* sub and superscripts: an expression following the ``^`` character
|
|
indicates exponentiation. To use superscripts in variables, the syntax
|
|
is ``b_x__d`` for the variable ``b`` with subscript ``x`` and super
|
|
``d``.
|
|
|
|
An example of a problem::
|
|
|
|
<symbolicresponse expect="a_b^c + b_x__d" size="30">
|
|
<textline math="1"
|
|
preprocessorClassName="SymbolicMathjaxPreprocessor"
|
|
preprocessorSrc="/static/js/capa/symbolic_mathjax_preprocessor.js"/>
|
|
</symbolicresponse>
|
|
|
|
It's a bit of a pain to enter that.
|
|
|
|
* The script-style math variant. What would be outputted in latex if you
|
|
entered ``\mathcal{N}``. This is used in some variables.
|
|
|
|
An example::
|
|
|
|
<symbolicresponse expect="scriptN_B + x" size="30">
|
|
<textline math="1"/>
|
|
</symbolicresponse>
|
|
|
|
There is no fancy preprocessing needed, but if you had superscripts or
|
|
something, you would need to include that part.
