Syllabus

What do we cover in this class? It will consist of three parts

  • Sequence and Limits
  • Metric space Topology
  • Differentiation and Riemann Integral

How to learn this course? One should

  • read the textbook and then come to lecture. In lecture, I will focus on motivations and examples, and key steps in the proofs, but I will leave many details as exercises for you to fill in.
  • participate in in-class group discussion. Since we don't have a discussion session, this is the chance for you to know your classmates. We will have 2-3 person small groups, and have discussion 20-30 minutes. For the first two weeks, we will use spatialchat.
  • participate in discord discussion. You can ask question about lecture and homeworks, and post your homework solutions here for others to comment.
  • [NEW] Student homepage. Our course has an area where you can create your own homepage. In your homepage, you can share your class notes, homework solutions, and whatever you think is relevant for this course.

How do we grade? Our grade will consist of

 participation (20%) + midterms (30%) + final (50%). 

Weekly homework is part of participation, and is not graded based on correctness.

It is hard to quantify participation, and I don't want to assign grade based on how many sentence you say. If one has to set a criterion, let's say, each week, you should

  • ask and answer at least one question on discord.
  • post your homework solution to to discord
  • in discord, comment at least two other student's homework posting.
  • You will also submit the homework to gradescope, where the grader or myself will give you comments.
  • make correction to the homework, and upload to your student homepage.

We will have two in-class midterms, and the one with the lower grade will be dropped.

The final is accumulative, 3-hour in class.

Textbook

We will be using three textbooks

Some other lecture notes might be useful

Journal

We will first cover sequence and limits, mainly following Ross and Tao-I

Then, we will cover metric space topology and continuous functions, where we will follow Rudin and Tao-II.

Finally, we will cover integration and differentiation, following Rudin.
