\section{SIND Sine Degrees Function}

\subsection{Usage}

Computes the sine of the argument, but takes
the argument in degrees instead of radians (as is the case
for \verb|cos|). The syntax for its use is
\begin{verbatim}
   y = sind(x)
\end{verbatim}
\subsection{Examples}

The sine of 45 degrees should be \verb|sqrt(2)/2|
\begin{verbatim}
--> sind(45)
ans = 
  <double>  - size: [1 1]
 0.7071067811865475  

\end{verbatim}
and the sine of \verb|30| degrees should be 0.5:
\begin{verbatim}
--> sind(30)
ans = 
  <double>  - size: [1 1]
 0.49999999999999994  

\end{verbatim}
