<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 & 1 \\ 1 & 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/>
