Description
HOW THIS COURSE WORK:
This course, Introduction to Calculus 3: Infinite Sequences and Series, includes the first three sections of my complete course in Calculus 3, including video, notes from whiteboard during lectures, and practice problems (with solutions!). I also show every single step in examples and theorems. The course is organized into the following topics:
Section 2: Infinite Sequences
Sequences
Convergence of a Sequence
Monotonic and/or Bounded Sequence
Section 3: Infinite Series
Series
Geometric Series
Telescoping Series
Harmonic Series
1. Test for Divergence
2. Integral Test
Estimating the Sum of a Series
3. Comparison Test
4. Limit Comparison Test
5. Alternating Test
Estimating the Sum of an Alternating Series
Absolute Convergence
6. Ratio Test
7. Root Test
Section 4: Power Series
Power Series
Radius of Convergence and Interval of Convergence
Representations of Functions as Power Series
Taylor Series and Maclaurin Series
Taylor's Inequality
Method 1: Direct Computation
Method 2: Use Term-by-term Differentiation and Integration
Method 3: Use Summation, Multiplication, and Division of Power Series
Applications of Taylor Polynomials
CONTENT YOU WILL GET INSIDE EACH SECTION:
Videos: I start each topic by introducing and explaining the concept. I share all my solving-problem techniques using examples. I show a variety of math issue you may encounter in class and make sure you can solve any problem by yourself.
Notes: In each section, you will find my notes as downloadable resource that I wrote during lectures. So you can review the notes even when you don't have internet access (but I encourage you to take your own notes while taking the course!).
Assignments: After you watch me doing some examples, now it's your turn to solve the problems! Be honest and do the practice problems before you check the solutions! If you pass, great! If not, you can review the videos and notes again.
HIGHLIGHTS:
#1: Downloadable lectures so you can watch whenever and wherever you are.
#2: Downloadable lecture notes and some extra notes so you can review the lectures if you don’t have a device to watch or listen to the recordings.
#3: Three complete problem sets with solutions (1 at the end of each section) for you to do more practices.
#4: Step-by-step guide to help you solve problems.
See you inside the course!

Who this course is for:
- Anyone who has completed Calculus 1 and Calculus 2 and wants to learn some more advanced calculus
- Current Calculus 3 students who are looking for extra help outside school
- Anyone who is not in the science stream but wants to study calculus for fun
Instructor
During my undergraduate years, I always looked forward to exams because I was well-prepared and found them rewarding. I know this isn’t the case for everyone, so I'm here to share my knowledge and help make your university journey a bit easier!
A bit about me:
I earned my BSc in Atmospheric Science and Physics, with a minor in Mathematics, from McGill University in 2018. I then completed my MSc in 2019 and my PhD in 2024, both in Physics at the University of Toronto. My research focuses on the impact of wind observations on global predictability, Arctic climate, and weather processes.
Since my second year of undergrad, I’ve gained extensive tutoring experience, working with students at Liberty Tutoring, supporting high school and university students through SUS Peer Tutoring and Saturday Programs, and working with private students both in person and online. I also served as a teaching assistant for math and physics courses at both the undergraduate and graduate levels from 2017 to 2024.
I look forward to seeing you in class!
