Plot the following polar equations in GNUPLOT:

\(r(\theta) = \theta^2 \sin(\theta/\pi)\)

\(r(\theta) = 3.75e^{-\theta/2.39}\)

Consider \(\theta\) range to be \(-\pi\) to \(\pi\) and the radial \(r(\theta)\) range to be \(-3 < r < 3\). Set different line types for the two functions. Put the title "Polar function plot". Save the plot in a suitable format.
