By James Stewart, Lothar Redlin, Saleem Watson

This top promoting writer staff explains techniques easily and obviously, with out glossing over tough issues. challenge fixing and mathematical modeling are brought early and strengthened all through, delivering scholars with a fantastic starting place within the ideas of mathematical pondering. complete and calmly paced, the publication offers whole insurance of the functionality suggestion, and integrates an important volume of graphing calculator fabric to aid scholars improve perception into mathematical rules. The authors' cognizance to element and readability, just like present in James Stewart's market-leading Calculus publication, is what makes this publication the industry chief.

Distance is always positive or zero, so we have 0 a 0 Ն 0 for every number a. Remembering that Ϫa is positive when a is negative, we have the following definition.

1Ϫa2 1Ϫb2 ϭ ab 1Ϫ42 1Ϫ32 ϭ 4 # 3 3. 1Ϫa2b ϭ a1Ϫb2 ϭ Ϫ1ab2 1Ϫ527 ϭ 51Ϫ72 ϭ Ϫ15 # 72 5. Ϫ1a ϩ b2 ϭ Ϫa Ϫ b Ϫ13 ϩ 52 ϭ Ϫ3 Ϫ 5 6. Ϫ1a Ϫ b2 ϭ b Ϫ a Ϫ15 Ϫ 82 ϭ 8 Ϫ 5 Property 6 states the intuitive fact that a Ϫ b and b Ϫ a are negatives of each other. Property 5 is often used with more than two terms: Ϫ1a ϩ b ϩ c2 ϭ Ϫa Ϫ b Ϫ c EXAMPLE 4 Using Properties of Negatives Let x, y, and z be real numbers.
