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

but the table below gives you a brief introduction to each.
HP 48 Plot Types
Plot Type and Description
Function
Plots true functions of a single
variable
( y
as a function of
x )
on
an ;;.’:y-coordinate system.
(Shown;
y — X
+ siii2.c)
Example
\rJ
n-J
i
Polar
Plots polar functions of a single
variable
{ r
as a function of
6 )
on
an ry-coordinate system.
(Shown; 3- = 2cos40)
Parametric
Plots the curve determined by
two parametric functions,
x { i )
and
y { t ) ,
that are combined a
complex-valued function,
f i t ) = x { t ) + i y ( t ) .
(Shown;
f i t ) =
3 sin 3i +
i2
sin 4t)
Differential Equation
Plots a phase plane of a
first-order differential eciuation at
given initial conditions. (Shown;
yt-phase of j/'(i) =
- 2i/’-')
Conic
Plots both solutions to the
quadratic equation representing a
conic section.
(Shown;
f i x , y ) =
5a;' -|- 3' — 18)
