specification of the HeadShape of an Arrow in terms of Plot or ParametricPlot \
the arrow should be rendered symmetrically. If $SymmetricalArrow=True then \
the Plot or ParametricPlot will be reflected across the x-axis: if \
$SymmetricalArrow=False it will not. The default value is \
$SymmetricalArrow=True."
