The Problem marker indicates problems for mastery of the current material and problems introducing new material. Each chapter starts with a brief discussion of the application or history of the content material. For example, the chapter on differentiation and its applications relates that differentiation was developed in the seventeenth century to handle problems involving velocity, tangent lines, and maximum and minimum values. Each section within a chapter starts with a brief introduction to the new material, followed immediately by an example or a problem. A demonstration shows how to find limits.
Problems then provide the students an opportunity to find the limits of various functions.
Each section ends with problems for practice with the material presented in the section. At the end of each chapter are problems for review of the entire chapter. ENC does NOT distribute this resource.
