Welcome
to
the
community
of
problem-solvers.
As
easy-to-use
as
a
calculator.
The
HP
48G
Series
calculators
use
a
special
graphical
interface,
inspired
by
current
generations
of
desktop
computer
software.
This
interface
guides
you
through
your
problem-solving
applications
smoothly
and
quickly.
Whether
you
are
solving
simultaneous
equations,
plotting
parametric
equations,
symbolically
solving
an
integral,
or
analyzing
a
set
of
data,
both
HP
48
models
work
in
a
familiar,
intuitive
way—performing
tasks
and
producing
readable
results.
As
powerful
as
a
computer.
The
HP
48G
Series
calculators
come
with
512K
of
built-in
ROM
and
up
to
128
KBytes
of
built-in
RAM.
All
HP
48
models
offer
you
the
problem-solving
power
of
specialized
computer
software
costing
hundreds
of
dollars—handheld
power
that
you
can
take
with
you
wherever
you
need
it.
The
HP
48
family
comes
with
memory
management
tools, a
structured
programming
language,
and
extensive
input/output
capabilities—all
characteristic
of
full-size
computers.

About
the
Quick
Start
Guide
The
HP
}8G
Series
Quick
Start
Guide
is
designed
to
help
you
learn
how
to
use
the
HP
48.
It
is
organized
into
lessons,
each
of
which
guides
you
through
a
series
of
examples
that
illustrate
how
to
accomplish
some
task.
Lessons
are
grouped
into
chapters.
The
HP
48G
Series
Quick
Start
Guide
doesn’t
provide
an
example
for
every
feature
of
the
HP
48.
But
it
should
provide
you
with
the
understanding
and
confidence
to
explore
the
nooks
and
crannies
for
yourself.
Please
refer
to
the
HP
48G
Series
User’s
Guide
if
you
want
to
explore
an
application
in
greater
detail.
Here
are
some
suggestions:
m
Read
lesson
1
first.
It
shows
you
how
to
set
up
the
machine
so
that
the
rest
of
lessons
in
the
machine
will
work
smoothly.
After
this,
explore
the
lessons
in
any
order
you
find
convenient.
m
Try
the
examples.
They’ll
give
you
a
good
idea
of
how
you
can
use
the
HP
48.
Actually
pushing
the
keys
and
watching
the
HP
48
work
while
following
along
is
the
fastest,
easiest
way
to
learn.
Occasionally,
an
individual
example
will
build
on
the
results
of
a
previous
calculation
or
example.
(This
is
especially
true
for
parameters
in
the
application
environments,
such
as
PLOT
or
SOLVE.)
If
you
notice
that
the screen
of
your
HP
48
doesn’t
match
the
screen
shown
in
the
example,
simply
correct
your
screen
and
then
continue
with
the
keystrokes
given
in
the
example.
m
Don’t
panic.
You
can
turn
the
HP
48
off
at
any
time—when
you
turn
it
on
again,
it’ll
be
ready
to
continue
where
you
left
off.
If
you
run
into
trouble,
see
chapter
10,
“If
Things
Go
Wrong,”
at
the
end
of
this
manual.

Lesson
1:
Getting
Ready
Here
are
a
few
things
to
do
to
prepare
the
HP
48
before
you
begin.
Turning
the

»
Press
(@)
(OFF)
to
turn
it
off.
The
key
is
a
shifted
version
of
the
key

The
calculator
will
also
turn
itself
off
if
you
haven’t
used
it
for
10
consecutive
minutes
in
order
to
preserve
its
batteries.
Unlike
some
calculators
(or
computers)
you
may
have
used,
the
HP
48
can
be
turned
off
at
any
time
without
risking
data
loss.

Mathematical
Objects
and
the
HP
48
The
mathematical
and
scientific
disciplines
use
a
wide
variety
of
objects
in
the
process
of
describing
and
solving
problems:
real
numbers
(sometimes
with
units
attached),
complex
numbers,
vectors,
matrices,
functions,
variables,
equations,
plots
of
many
kinds,
points,
sequences,
words
and
sentences,
programs,
and
so
forth.
The
HP
48
can
use
all
of
these
objects

Introducing
the
HP
48

By
design,
the
HP
48
makes
it
easy
to
move
between
one
type
of
object
and
another
as
one
solves
a
problem,
explores
data,
or
communicates
results.
It
accomplishes
this
by
using
an
object
stack
(or
“stack,”
for
short).
Envision
the
stack
as
a
special
kind
of
“card
box”
in
which
the
HP
48
organizes
all
of
the
objects
it
uses
in
the
course
of
calculating,
solving,
plotting,
and
evaluating.
Each
object,
no
matter
its
size,
occupies
exactly
one
“card”
in
the
“card
box.”
The
object
on
the
first
“card”
is
said
to
be
on
“stack
level
1,”
the
object
on
the
second
card
is
on
“stack
level
2,”
and
so
forth.
The
stack
can
contain
any
number
of
objects—from
zero
to as
many
as
available
memory
permits.
The
main
display
of
the
HP
48
is
the
stack
display.
It
1s
merely
a
window
showing
you
a portion
of
the
stack
at
a
time.

enter
and
“leave”

stack
at

When
you
enter
a
new
object,
you
place
it
in
the
front
of
the
“card
box”
(stack
level
1)
thereby
pushing
objects
already
in
the
“box”
farther
to
the
back
(increasing
their
stack
levels
each
by
one
in
the
process).

Editing
an
Object
in
the
Command
Line
You
probably
noticed
that
as
soon
as
you
begin
typing
in
an
object,
it
appears
“below”
the
stack
on
a
line
of
its
own.
This
line
is
the
command
line.
Actually,
the
command
line
is
more
than
one
line.
It
expands
as
needed
to
accommodate
objects
of
any
size.
Objects
in
the
process
of
being
created
stay
on
the
command
line
until
you
press
(ENTER),
at
which
point
they
are
placed
onto
the
stack
and
the
command
line
disappears.
Making
typing
errors
while
creating
numbers
and
other
objects
is
a
common
problem,
but
one
that
is
easily
fixed.
After
all,
the
command
line
is
designed
to
be
a
preliminary
work
area
where
you
can
create,
edit,
or
refine
an
object
before
you
decide
to
enter
it,
thus
declaring
it
“ready.”
As
long
as
you
see
the
command
line,
you
can
edit
whatever
you're
in
the
process
of
creating.
Here’s
a
list
of
the
editing
keys
and
what
they
do:
Erases
the
entire
Command
Line,
causing
it
to
disappear
until
you
start
typing
again.
Moves
the
cursor
(#)
to
the
left.
Moves
the
cursor
to
the
right.
Moves
the
cursor
to
the
line
above
(for
objects
requiring
more
than
one
line).
Moves
the
cursor
to
the
line
below
(for
objects
requiring
more
than
one
line).
Erases
the
character
to
the
left
of
the
cursor.
F
©
=
OO
DEL
Erases
the character
underneath
the
blinking
cursor.
Each
of
these
keys
are
editing
keys
only
while
you
are
using
the
command
line.
At
other
times,
each
key
performs
the
action
printed
above
it.
When
there’s
no
command
line,
(«)
becomes
(DROP),
becomes
(CLEAR)
and
so
forth.
This
allows
you
quicker
access
to
these
operations
(you
need
not
press
the
@
shift
key
first).

Removing
Objects
from

Stack
Example:
Now
remove
(“drop”)
objects
from
the

Step
1:

just
the
object
in level
1.
Notice
that
all
other
objects
drop
a

the
process.
