The text was published in 1998 by John Wiley and Sons, Inc. (ISBN 0-471-24050-8).

It was written by C-K. Cheung, G. E. Keough, C. K. Landraitis,
and R. H. Gross (all of Boston College). C-K, Jerry, and Charlie
have taught *Mathematica* to undergraduate mathematics majors
at BC several times, and all of us (Rob included!) have used *Mathematica*
as an essential component of undergraduate electives that we teach.

An errata list for the second printing of this text follows

Comment. The first printing can be identified by the date "January, 2001" on page vi of the Preface.

- At this time, we have no listing of errors.

Comment. The first printing can be identified by the date "March, 1998" on page vi of the Preface.

- pages 90 - 93. Information stated about SphericalPlot3D is
incorrect as stated. Our description of the angles used in SphericalPlot3D
is completely reversed. We are, or course, to blame for this
oversight, but it was created because what mathematicians typically
call "theta" is actually what physicists call "phi,"
and vice-versa.
*Mathematica*is more oriented towards the physicists here.- page 90. The first angle mentioned in the SphericalPlot3D
command must be the
**vertical angle**, measured from the positive z-axis. The second angle must be the**horizontal, polar angle**in the xy-plane, measured from the positive x-axis.

Thus, the text can be corrected if lines 4 and 5 are rewritten to say that "theta" is the vertical angle, measured from the z-axis, and "phi" is the horizontal angle measured from the x-axis. (***This page has been redone and the angles properly clarified in the second printing, and a note has been added about the potential confusison of the two angles between mathematicians and physicists.***) - page 93. Due to the error above, the last question/answer sequence on this page may appear to be confusing, but it is actually correct as it stands with this correction in the understanding of the angles "theta" and "phi." (***This answer has been slightly expanded and clarified in the second printing.***)

- page 90. The first angle mentioned in the SphericalPlot3D
command must be the
- page 174. The two graphics shown on this page contain a harmless inconsistency. The phrase "Calculus Examples" appears at the top of the first graphic, but it has morphed into the phrase "Calculus Section" in the second graphic. (***This has been fixed in the second printing.***)
