HP 48G Series

Lesson 25: Introducing the Plot Types
There are fifteen different kinds of plots that the HP 48 can draw.
Each of them is discussed in detail in the HP 48G Series User's
Guide, but the table below gives you a brief introduction to each.
HP 48 Plot Types
Plot Type and Description Example
Function
Plots true functions of a single
variable (y as a function of z) on
(Shown: y = x + sin 2x)
an
ry-coordinate
system.
1
Polar
Plots polar functions of a single
variable (7 as a function of ) on —
an ry-coordinate system.
(Shown: r = 2 cos 40)
Parametric
Plots the curve determined by
two parametric functions, x(?)
and y(t), that are combined a
complex-valued function,
F(t) = a(t) +iv(t).
(Shown: f(t) = 3sin3t +12sin4t)
Differential Equation
Plots a phase plane of a
first-order differential equation at
given initial conditions. (Shown:
yt-phase of y(t) = The — 2%)
Conic
Plots both solutions to the
quadratic equation representing a
conic section.
(Shown: f(x,y) = 52% + 3% — 18)
