This text freely uses and refers to numerical and graphical
computations, but it is independent of any particular technology. Any of
the familiar highlevel productsMathematica, Maple, Deriveare certainly sufficient, but hardly necessary. Many
graphing calculators (e.g., the TI81, 82, and 85, the HP48G, etc.)
and specialpurpose microcomputer software packages are adequate.
Our use of technology is most conveniently described in terms of functionalities. The requirements for Calculus I and Calculus II
differ somewhat:
 Calculus I:

Chapters 15 (the traditional content of Calculus I) draw freely on
machine graphics; almost any uptodate form will do.
Most graphing calculators would suffice; so would almost
any flexible microcomputer graphing program, such as MasterGrapher
or MicroCalc.
 Calculus II:

To make the best use of the remaining (Calculus IInot
covered in this volume) material, students
will require access to a modest level of numerical computation (mainly
for estimating analytic quantities: integrals, series, etc.) Many
microcomputer software packages provide the necessary functionality; so
do some programmable graphing calculators. In addition, access to
simple symbolic operations (e.g., formal differentiation, Taylor series
expansion) is desirable, but not strictly necessary.
