An Atlas of Functions with Equator, the Atlas Function Calculator

From the reviews of the second edition:

"The book is devoted to functions such as quadratic and cubic polynomials, absolute value, square roots, etc. … the Atlas comes with software for computing the functions described in the book. … the Atlas is valuable as a reference, it also contains a large amount of expository text. … The Atlas seems to have been written for the reader who is not in such a hurry and who might enjoy looking around a bit." (John Cook, The Mathematical Association of America, March, 2009)

"This is a compilation of several hundred functions that are frequently used by engineers, scientists, and mathematicians to obtain a quantitative result. … Each chapter in this handbook discusses a function or a family of related functions for a total of 65 chapters. … Each chapter contains definitions and properties for each function along with color graphs … . Engineers, scientists, and mathematicians will find this reference book to be a handy resource for manyyears." (Electrical Insulation Magazine, 2009)

"This book provides elementary and basic information on several hundred functions … . a combination of a book and software is useful for scientists concerned with the quantitative aspects of their field. … layout of the book is modern with very nice colorful graphs or surfaces of functions. Each chapter contains a lot of information about the functions studied in that chapter. … This book defends well its place in the mathematical literature." (Matti Vuorinen, Zentralblatt MATH, Vol. 1167, 2009)

“This is the second edition of a handbook with same title … . There are numerous other improvements throughout this new edition but the objective remains the same to provide the reader regardless of his or her discipline with a succinct compendium of information about all the common mathematical functions in use today. … The layout of the book is excellent and it is a pleasure to see the glossy paper and the very high quality graphs. The inclusion of Equator is a useful contribution.” (Mourad E. H. Ismail, Mathematical Reviews, Issue 2010 f)
