We begin this course in Chapter 2 of your ebook. Sections 2.1, 2.2, and 2.3 is focused on reviewing functions. We will start with fresh new look at brief calculus in Section 2.4, which is titled "Limits"! Throughout the course, I will attempt to partition the video lecture/examples into two parts: 1. computations, and 2. applications. If there are graphs of concern, I am going to try to put those with computations. Applications is also known as "word/story problems". I like to view them as math in other context or subjects.

The focus from my video lectures is to demonstrate and share some mathematical writing and thinking. I will not be doing every type of homework problem for you. It will be very wise for you to preview the ebook/textbook yourself to gather vocabulary terms and other examples that are necessary to understand the videos and prepare you for practice. Feel free to pause/replay the videos to take better notes. I turned on the WebAssign feature to provide the ebook and some videos. The videos provided in WebAssign are NOT by me. Please disregard those videos in WebAssign as a first priority. Use my videos as a first priority and WebAssign videos as a second priority. Trust me, more often than not, my writing is more thorough and better structured than what is provided in WebAssign. My videos will establish the writing expectations expected on the Midterm and the Final Exams.

The examples in my videos are designed to give you hints for your WebAssign practice. Like I said, I cannot give hints to every single problem, but I tend to focus on problems that I know students commonly ask about. Your WebAssign homework was designed by me as well. These problems that are assigned to you were handpicked by me. The numbers cited below reference the problem numbers from the ebook and is also included in your WebAssign homework.

Video by Wu, Section 2.2 (Computations); Designed to give hints for 6, 22, 28, 30, 32, 38, 40, 50, 52

Objectives: Reviewing the algebra of functions, which includes composition of functions. Be able to simplify the difference quotient.

Video by Wu, Section 2.2 (Applications); Designed to give hints for 55, 57

Objectives: Establish the habit of using function notation for applications, especially in a calculus course! Recognize independent versus dependent variables.
