[mg4773] Vertical Lines (Boundaries)
Wants to Plot the equation y=x^2 and show boundaries at x=1 and x=2
(vertical lines).
Larry,
Prolog and Epilog are useful for this sort of thing:
Plot[x^2,{x,0,2},
Epilog ->Line[{{1/2,-1},{1/2,8}}],
PlotRange->{-1,6}
]
PlotRange is needed because the region displayed does not take
account of Epilog.
