between two plotted points. The default step-size for
C is an interval equal to 1 pixel.
When checked, the step-size is interpreted to represent
pixels. When unchecked (default) the step-size is
interpreted to represent units.

Special Notes
For conic plots, the HP 48 actually plots the two branches of
the conic section separately. This may introduce one or two
discontinuities in the connected graph. Specifying a smaller step size
(decreasing the interval between plotted points) helps eliminate
visual discontinuities.
m If flag -1 (Principal Values) is set, the Conic plot will only display
its principal branch (half of the plot). Clear flag -1 and redraw to
plot the entire conic section.
Equations that are higher than second-order in the independent
or dependent variable are converted to their second-order Taylor
approximations before being plotted.
Conic is a useful plot type for plotting systems of equations
involving two variables where none of the equations are higher than
second order in either variable (see Example 2 in “Truth Plots" for
a sample application).

After plotting, press (CANCEL) (r»]f PLOT) to review the PLOT forms
that generated the plot. Experiment by changing values or settings
and redrawing the plot.
