Welcome

the

HP·28S

Congratulations!

With

the

HP-28S

you

can

easily solve

complicated

problems,

including

problems

you

couldn't

solve

a calculator

be-

fore.

The

HP-28S

combines

powerful

numerical

computation

with

new

dimension-symbolic

computation.

You

can

formulate

problem

symbolically, find a symbolic

solution

that

shows

the

global

behavior

the

problem,

and

obtain

numerical results from

the

symbolic solu-

tion.

The

HP-28S

offers

the

following features:

• Algebraic

manipulation.

You

can

expand, collect,

rearrange

terms

expression,

and

you

can

symbolically solve

equation

for a

variable.

• Calculus.

You

can

calculate derivatives, indefinite integrals,

and

definite integrals.

• Numerical solutions. Using

Solve

the

HP-28S, you

can

solve

expression

equation

for

any

variable.

You

can

also solve a

system

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

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.

Welcome

The

HP-28S Owner's Manual (this

manual)

contains

three

parts.

Part

"Fundamentals,"

demonstrates

how

work

some

simple

problems.

Part

"Summary

of Calculator Features,"

builds

part

1 to

help

you

apply

those examples to

your

own

problems.

Part

3, "Program-

ming," describes

programming

features

and

demonstrates

them

in a

series

programming

examples.
