+<h2>Example: Symbolic Math Response Problem</h2>
+
+<p>
+A symbolic math response problem presents one or more symbolic math
+input fields for input.  Correctness of input is evaluated based on
+the symbolic properties of the expression entered.  The student enters
+text, but sees a proper symbolic rendition of the entered formula, in
+real time, next to the input box.
+</p>
+
+<p>This is a correct answer which may be entered below: </p>
+<p><tt>cos(theta)*[[1,0],[0,1]] + i*sin(theta)*[[0,1],[1,0]]</tt></p>
+
+<script>
+from symmath import *
+</script>
+  <text>Compute [mathjax] U = \exp\left( i \theta \left[ \begin{matrix} 0 &amp; 1 \\ 1 &amp; 0 \end{matrix} \right] \right) [/mathjax]
+      and give the resulting \(2 \times 2\) matrix. <br/>
+      Your input should be typed in as a list of lists, eg <tt>[[1,2],[3,4]]</tt>. <br/>
+       [mathjax]U=[/mathjax] <symbolicresponse cfn="symmath_check" answer="[[cos(theta),I*sin(theta)],[I*sin(theta),cos(theta)]]" options="matrix,imaginaryi" id="filenamedogi0VpEBOWedxsymmathresponse_1" state="unsubmitted">
