\label{Function_Plot_Response_Vector_Sum_Rule}

\begin{itemize}
\item
``Index/Name'' - This is an internal label for the rule.  Something must be entered here, and it must be different for each rule.  This same value will be used to add a conditional hint.

\item
``Comma-spearated list of vectors'' - List all of the vectors that should be added up to be tested.

\item
``Length'' - How long the sum of these vectors should be.

\item
``Absolute error length'' - How accurate the length must be to get the answer correct.

\item
``Angle'' - What direction should the sum of these vectors point.  All values are measured in degrees, counterclockwise starting at the positive x-axis.  Values must be $0\le\theta<360$

\item
``Absolute error angle'' - How accurate the angle must be to get the answer correct.
