Welcome
to
the
HP·28S
Congratulations!
With
the
HP-28S
you
can
easily solve
complicated
problems,
including
problems
you
couldn't
solve
on
a calculator
be-
fore.
The
HP-28S
combines
powerful
numerical
computation
with
a
new
dimension-symbolic
computation.
You
can
formulate
a
problem
symbolically, find a symbolic
solution
that
shows
the
global
behavior
of
the
problem,
and
obtain
numerical results from
the
symbolic solu-
tion.
The
HP-28S
offers
the
following features:
• Algebraic
manipulation.
You
can
expand, collect,
or
rearrange
terms
in
an
expression,
and
you
can
symbolically solve
an
equation
for a
variable.
• Calculus.
You
can
calculate derivatives, indefinite integrals,
and
definite integrals.
• Numerical solutions. Using
HP
Solve
on
the
HP-28S, you
can
solve
an
expression
or
equation
for
any
variable.
You
can
also solve a
system
of
linear
equations. With
multiple
data
types, you
can
use
complex
numbers,
vectors,
and
matrices as easily as real
numbers.
• Plotting.
You
can
plot
expressions,
equations,
and
statistical data.
•
Unit
conversion.
You
can
convert
between
any
equivalent
combina-
tions
of
the
120
built-in
units.
You
can
also
define
your
own
units.
• Statistics.
You
can
calculate single-sample statistics,
paired-sample
statistics,
and
probabilities.
• Binary
number
bases.
You
can
calculate
with
binary, octal,
and
hexadecimal
numbers
and
perform
bit
manipulations.
• Direct
entry
for algebraic formulas,
plus
RPN
logic for interactive
calculations.
