Key differences between 13th and 12th editions

• Period between current and previous publications: 4 years (2011 vs 2007).
• The Thirteenth edition of Algebra and Trigonometry textbook hasn't changed much from its predecessor.
• About 650 new exercises and 11 new examples - in other words almost 20% of the exercises are new or updated.
• New Chapter Tests feature at the end of each chapter contain questions that are representative of exercises in the sections, as well as unique concept questions. These new items provide an additional source of exam questions and practice for students.
• Arrow notation is introduced earlier in Section 2.2 and revisited more often in 13th Edition, bolstering precalculus content for better preparation for calculus topics.
• New Examples:
• find the inverse of a rational function (Section 4.1, with the method for checking presented in a marginal note)
• predict a quantity using the decay formula (Section 4.3)
• how to show that an equation is not an identity (Section 6.1)
• use the subtraction formula for the cosine to find an exact value when given an exact trigonometric value and the sign of another trigonometric function (Section 6.3)
• how to find double angle values of other trigonometric functions given that the tangent of an angle is a constant (Section 6.4)
• new type of probability problem (Section 10.8).
