<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">I attached one of the problems using function plot response that I’ve created and used in my Electric Circuits class.<o:p></o:p></span></p>
<p class="MsoNormal"><a name="_MailEndCompose"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">It works fine except there are several peculiarities that one has to keep in mind when using function plot response.<o:p></o:p></span></a></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">Most of them I’ve learned by trial and error.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">1. Function plot problem cannot be a part of composite page.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">2. There are certain issues with checking “prior tries” in case student would say that his/her previous try was correct. Lon-CAPA stores prior tries for function plot response
in a form of some array that I wasn’t be able to read or interpret.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">3. Once in a while (one out of 40 students) encounter strange issue: after they submit the plot, LON-CAPA response is “not a function”. No matter what you do after that, it would
still display this message: change the curve, do not change the curve etc. It does not depend on the OS – windows or MAC. We were not able to figure out what causes it.
