Describe the plot produced by the following:
\begin{lstlisting}
In []: x = linspace(0, 2*pi, 50)
In []: plot(x, cos(x), 'go')
\end{lstlisting}
Note: Do not draw it, just describe the plot
\end{frame}
\begin{frame}
\frametitle{\incqno }
How will you plot the previous graph with line width set to 3? How will
you set the $x$ and $y$ labels of the plot?
\end{frame}
\begin{frame}
\frametitle{\incqno }
How will you set the x and y axis limits so that the region of interest
is in the rectangle $(0, -1.5)$ (left bottom coordinate) and $(2\pi,
1.5)$ (right top coordinate)?
\end{frame}
\begin{frame}
