Derivatives, the chain rule, implicit differentiation, higher derivatives. Exponential functions, inverse functions, and their derivatives. The mean value theorem, monotonic functions, concavity, and points of inflection. Applied maximum and minimum problems. Pre- Requisites and Entrance Requirements Passing grade in Math 3 (Precalculus) or Applied Mathematics and Statistics 3, or mathematics placement examination (MPE) score of 400 or higher; or AP Calculus AB exam score of 3 or higher. Course Learning Objectives 1. Understand the concept of an instantaneous rate of change and the derivative of a function 2. Learn how to calculate derivatives explicitly and implicitly and to master how derivatives affect the behavior of a function 3. Master the application of the derivative notion to optimization problems Learning Activities The course uses a learning management system (LMS) to organize content and act as a portal to various other platforms including an interactive e- textbook, a homework platform with immediate feedback, and a discussion forum. There are ten weekly modules in the course, but these can be reconfigured to accommodate a shorter

2 summer session term. Within each module, there are 1-3 lessons and each of these lessons outline four learning activities. To be successful in this course, students must actively engage in all four activities: 1. Read the textbook 2. Watch the video lectures 3. Do the homework 4. Interact with others 1. Readings Each lesson indicates the required reading and links to the interactive e- textbook based on Jon Rogawski's textbook, Calculus, Early Transcendentals, 2nd ed. As students read each section in the e- book, they encounter graded progress- check questions as well as supplemental exercises. Progress- check questions provide immediate feedback and are set up to allow three attempts. 2. Videos Each lesson also links to short video lectures that explain major course concepts and techniques and provide examples. Students are encouraged to alternate between viewing the videos and reading the corresponding sections in the e- book. Students can pause or rewind lecture videos if they don t understand content covered. They can also come back for review at any time. In the first module, students are encouraged to watch supplemental lectures that provide context and historical background to the mathematics covered in the course. While this content is not covered on assessments, it is an integral part of the course, providing students with a deeper understanding of the concepts covered in the regular lectures. 3. Homework Each lesson indicates the required homework assignment and links to the online homework system. This system provides immediate feedback on answers submitted and allows unlimited attempts. In preparation for exams, students are provided with optional ungraded practice materials. 3. Interaction The course includes an on- line discussion forum centered on questions relating to the video lectures, homework, reading, and course logistics. In addition, the teaching staff Page 2

3 hold regular on- line and in- person office hours, as well as an all day drop- in section. Finally the course includes student- run, location- based study groups with corresponding online group interaction spaces in the LMS. Details on how to participate are outlined on the lesson pages and other dedicated pages in the LMS. Course Modules.
