# New in Version 4.0

Learn about APEX Calculus for Quarters at bottom.

• Chapter 14: Vector Analysis. Covers line integrals, Green's, Stokes' and Divergence Theorems, etc. See below for section headings. This content is included in APEX Calculus 3; as many schools do not teach this content, it is omitted in APEX Calculus 3*, the abridged edition. (See the Download and Purchase pages for more information.)
• Cylindrical and Spherical Coordinates. A new section on triple integration with these coordinate systems is included in Chapter 13.
• Better numbering of of Definitions, Theorems, etc. Now "Definition 12.4.3" refers to the 3rd Definition of Chapter 12, Section 4.
• Better exercise sets. The main adjustment here is that all question sets (i.e., "In Exercises 17-25, do ..." ) there are an even number of problems and the first problem number is odd. New problems have been added. A wholesale changing of the exercises to justify a new edition did not occur.
• "Small" corrections. Numerous misspellings, grammatical errors, dropped minus signs, etc., have been fixed. (Many thanks to all who submitted corrections.)
• "Large" corrections. There were several places in Version 3.0 where a definition or theorem just was not right. A partial list of topics affected: one-sided limits, definition of increasing/decreasing functions, limits of multivariable functions, and multivariable second derivative test.

# Content of APEX Calculus, Version 4.0

APEX Calculus comprises 14 chapters; each chapter and section is listed below. This text was written to have the same basic organization as most traditional calculus textbooks.

The whole text is 972 pages long. For multiple reasons (lower cost per semester, lower weight per semester, increased likelihood of students bringing their text to class, etc.), APEX Calculus has been divided into smaller volumes in two ways.  One division is intended for schools on a semester system, split roughly along traditional "Calc 1, 2 & 3" lines. The other division is intended for schools on the quarter system.

APEX Calculus 1, 2 & 3:

• Calculus 1: Chapters 1 through 6.1
• Limits through Integration by Substitution
• Calculus 2: Chapters 5 through 8
• Integration through Sequences and Series
• Calculus 3: Chapters 9 through 14
• Curves in the Plane through Vector Analysis
• Calculus 3*: Abridged, Chapters 9 through 13 (for those not needing Vector Analysis)
• Curves in the Plane through Multiple Integration

APEX Calculus for Quarters Q1, Q2, Q3 & Q4:

• Q1: Chapters 1 through 4
• Limits, Derivatives and their applications
• Q2: Chapters 5 through 7, plus a Differential Equations appendix
• Integration, techniques and applications
• The appendix offers an introduction to DE's, covering Euler's method, separable and first-order DE's, along with an introduction to mathematical modeling. (Written by Ross Magi of Walla Walla University.)
• Q3: Chapters 8 through 11
• Sequences and Series, Parametric Equations, Polar Coordinates, Vectors and Vector-Valued Functions
• Q4: Chapters 12 through 14
• Multivariable Functions, Partial Derivatives, Iterated Integration and Vector Analysis

If these divisions do not match up well with your department's division of Calculus material:

• Tell me so I know what people are most interested in,
• Consider editing the source files at GitHub to create your own version, and/or
• Consider "just making it work as is"; while not ideal, the book is still a great text at a great price.
