If (again, IF) you are a student at Daytona Beach Community College, considering taking this course, this is THE textbook written by the professor. Interesting side note, Rr. Riban periodically pulls the copyright in order to renegotiate the price DOWN, because he believes textbooks are overpriced. The book is essentially the same, no matter the edition, so any book you can find can be used in the course. What a great philosophy from a college science professor.
