Finite Mathematics and Calculus with Applications, Ninth Edition, by Lial, Greenwell, and Ritchey, is our most applied text to date, making the math relevant and accessible for students of business, life science, and social sciences. Current applications, many using real data, are incorporated in numerous forms throughout the book, preparing students for success in their professional careers. With this edition, students will find new ways to get involved with the material, such as “Your Turn” exercises and “Apply It” vignettes that encourage active participation. The MyMathLab® course for the text provides additional learning resources for students, such as video tutorials, algebra help, step-by-step examples, and graphing calculator help. The course also features many more assignable exercises than the previous edition.
- A wide variety of applications reference real data from articles in newspapers, journals, and websites. Examples with recent data help students learn how the mathematics is applied to their field of study, immediately addressing the question “why are we learning this?”

- Reference Tables for Exercises appear in the back of the book, next to the answers to odd-numbered exercises. These tables correlate exercises to a specific example in the text; for review exercises, they refer to the section in the chapter where the topic of the exercise is first discussed.
- More than 20% of the applications and 32% of the examples are new or updated. In addition, the authors have added or updated more than 600 exercises.
- Chapter R (Algebra Reference): The flow of the material was improved through the reordering of some exercises and examples. Exercises were added to section R.1 (on performing algebraic operations) and section R.5 (on solving inequalities).
- Chapter 1 (Linear Functions): Changes in the presentation were made throughout to increase clarity, including adding some examples and rewriting others. Terminology in Section 1.2 (Linear Functions and Applications) was adjusted to be more consistent with usage in economics.
- Chapter 2 (Systems of Linear Equations and Matrices): Section 2.1 (Solution of Linear Systems by the Echelon Method) was changed so that only systems of two equations are solved by the echelon method, while systems with three or more equations are postponed until the Gauss-Jordan method in Section 2.2 (Solution of Linear Systems by the Gauss-Jordan Method). The discussion of subtraction of matrices in Section 2.3 was simplified.
- Chapter 3 (Linear Programming: The Graphical Method): The concept of bounded and unbounded regions was moved from Section 3.2 (Solving Linear Programming Problems Graphically) to Section 3.1 (Graphing Linear Inequalities), where such regions are first encountered. An Extended Application on sensitivity analysis was added to this chapter.
- Chapter 4 (Linear Programming: The Simplex Method): Exercises 25–30 in Section 4.1 (Slack Variables and the Pivot) were modified to clarify the role of slack variables. Exercise 30 in Section 4.2 was modified to amplify how multiple solutions may arise. The method for handling ties in nonstandard problems in Section 4.4 (Nonstandard Problems) was improved.
- Chapter 5 (Mathematics of Finance): In Section 5.1 (Simple and Compound Interest), examples and accompanying exercises were added covering how to solve for the interest rate and how to find the compounding time, both with a graphing calculator and with logarithms. The explanation of the rule of 70 and the rule of 72 was improved. Material on continuous compounding was also added to Section 5.1. In Section 5.3 (Present Value of an Annuity; Amortization) an example and accompanying exercises were added discussing how a loan can be paid off early.
- Chapter 6 (Logic): Many exercises in this chapter were revised so that the information would be more relevant to students. For example, tax references include scholarships, tuition, paychecks, reporting tips, filing taxes, inheritances, and tuition deductions; law references include car accidents, contracts, lawsuits, driver’s license, and marriage; and warranty references cover the iPhone™ and eBay®. In Section 6.5 (Analyzing Arguments and Proofs), applications were revised to give more diversity in topics.
- Chapter 7 (Sets and Probability): Empirical probability was moved from Section 7.4 (Basic Concepts of Probability) to 7.3 (Introduction to Probability) so that methods for determining probability are contained in the same section. In Section 7.4, probability distributions are emphasized more and a probability distribution example was added. In Section 7.6 (Bayes’ Theorem) the introduction to Bayes’ Theorem was rewritten for brevity and clarity.
- Chapter 8 (Counting Principles; Further Probability Topics): The notation for combinations was changed from (nr) to C(n, r) to be more current and consistent with our notation throughout the book. Section 8.3 (Probability Applications of Counting Principles) now includes an example illustrating probabilities using permutations and using the multiplication principle.
- Chapter 9 (Statistics): In Section 9.1 (Frequency Distributions; Measures of Central Tendency) a new example was added, illustrating a case where the median is a truer representation of data than the mean.
- Chapter 10 (Nonlinear Functions): The material in Section 10.1 (Properties of Functions) on the Dow Jones Average was updated. Material on even and odd functions was added. Material on identifying the degree of a polynomial has been rewritten as an example to better highlight the concept. The discussion of the Rule of 70 and the Rule of 72 was improved. A new Extended Application on Power Functions has been added.
- Chapter 11 (The Derivative): In Section 11.1 (Limits), the introduction of limits was completely revised. The opening discussion and example were transformed into a series of examples that progress through different limit scenarios: a function defined at the limit, a function undefined at the limit (a hole in the graph), a function defined at the limit but with a different value than the limit (a piecewise function), and then finally, finding a limit when one does not exist. New figures were added to illustrate the different scenarios. In Section 11.2 (Continuity) the definition and example of continuity has been revised using a simple process to test for continuity. The opening discussion of Section 11.5 (Graphical Differentiation) showing how to sketch the graph of the derivative given the graph of the original function was rewritten as an example.
- Chapter 12 (Calculating the Derivative): The introduction to the chain rule was rewritten as an example in Section 12.3 (The Chain Rule). Exercise topics were revised to cover subjects such as worldwide Internet users, online learning, and the Gateway arch.
- Chapter 13 (Graphs and the Derivative): In Section 13.1 (Increasing and Decreasing Functions) the definition of increasing/decreasing functions has been moved to the beginning of the chapter, followed by the discussion of using derivatives to determine where the function increases and decreases. The determination of where a function is increasing or decreasing is divided into three examples: when the critical numbers are found by setting the derivative equal to zero, when the critical numbers are found by determining where the derivative is undefined, and when the function has no critical numbers.
- Chapter 14 (Applications of the Derivative): Changes in the presentation were made throughout to increase clarity and exercise sets were rearranged to improve progression and parity.
- Chapter 15 (Integration): The social sciences category of exercises was added to Section 15.1 (Antiderivatives), including the topics of bachelor's degrees and the number of females earning degrees in dentistry. Color was added to the introduction and first example of substitution in Section 15.2 (Substitution) to enable students to follow the substitution more easily.
- Chapter 16 (Further Techniques and Applications of Integration): In addition to exercises based on real data being updated, examples in this chapter were changed for pedagogical reasons.
- Chapter 17 (Multivariable Calculus): Graphs generated by Maple™ were added to Examples 2 and 4 in Section 17.3 (Maxima and Minima) to assist students in visualizing the concept of relative extrema. Material covering utility functions was added to Section 17.4.
- Chapter 18 (Probability and Calculus): In Section 18.2 (Expected Value and Variance of Continuous Random Variables), an example on how to calculate the probability within one standard deviation of the mean (which is required in many of the exercises) was added. The Social Sciences category was added to the exercise set, with exercises on calculating the median, expected value, and standard deviation. Topics include the time it takes to learn a task and the age of users of a social network.
