During Spring 2020, I was teaching MATH119 (Section 3) at U-3 auditorium. Due to the size of the auditorium, I was using a tablet connected via HDMI to the screen in U-3 and posted the lecture notes at this page at the request of some students.

In the middle of semester, due to the global COVID-19 crisis, the lectures were held online starting from March 23, 2020. The videos of online lectures as well as their lecture notes are also posted on this page.

I would like to point out that **the notes on this page are the lecture notes and not the recitation notes**. (The recitation videos and notes can be reached from this link.) *You should keep in mind that*

*The textbook of the course is Adams’ Calculus book, so you should***not**treat the material in these notes as the “official” course notes. It is possible that Adams and I take different approaches to cover certain topics.*During lectures, there is commentary besides what I write on the tablet. For example, I may be emphasizing important points and explaining common mistakes and how to approach to a specific type of problem. Consequently, there is some (orally communicated) material present in the lectures that is***not**included in these notes, which means that you should not just focus on these notes.*Use the textbook along with these lecture notes to study and solve the suggested problems together with past exam questions.***Try to understand and not memorize.***There may be errors and typos, so use these notes with caution.*
