Hi all,

I have finished grading the midterm and published the grades on Catalyst. Exams will be handed back to you on Monday.

Here are some common mistakes I noticed:

1. How to negate quantifiers and bounded quantifiers.

2. How to show set A is a subset of set B.

3. The order of different quantifiers and what they mean.

4. How to show a statement is false.

5. What are hypothesis and conclusion.

Lectures and exams are designed to work for a general group, but each one of you is an individual, and what works for general people doesn’t necessarily work for you. Please come and talk to me, and we can analyze what works for you, and help you succeed in this class. I am here to help, not to judge. As long as you are willing to work with me, I am available to help!

Grades in this class is curved, and I will award improvement points if you did significantly better on the final, so no need to freak out about your grades. Come and get help from me!!

# Practice Midterm

Hi all,

We will have our midterm exam on Friday, July 24 in our normal classroom during normal lecture time. We will review on Wednesday, by doing the practice midterm exam: su_15_300_mid_practice

I will have extra office hours on Wednesday 12.00-13.00, 14.00-15.00 or by appointment. Just shot me an email 30 minutes before you come over!

I will be around on Thursday until 13.20, and available via email after that. Feel free to email me a picture of your work with questions!

# Review of Chapters 1~3

Hi all,

This is a reading review of brief sum up of the chapters 1 to 3: Reading_review

If you want to practice for the midterm, find some old exams here. Of course, topics we have not covered (such as functions, proof by induction, etc) will not be covered in the midterm.

Hi all,

Please check your grades on Catalyst (both homework grades are published) and contact me if there are any mistakes. You can correct your grades with me by showing me your original homework anytime before the last week of class.

If you have not turned in all the homework yet, please contact me. Homework grades take up a large portion of your grades, so please let me know if you need/want any help with them. Just come and talk to me, I want to make sure you know what is going on.

# Midterm on July 24th

HI all,

A reminder: we will be having a midterm exam next Friday, July 24th.

There is no homework due next Wednesday, but the exam will cover everything before Chapter 4. To review sections 3.4-3.7, do these problems:

3.4: (9*,10),11,12,13

3.5:( 1*,2), (10,11*), (19*,20), 26*,27,28*,30*

3.6: (1*,2), 9

3.7: 3, 6, (7*,8),9*

You might have noticed that some of these problems are grouped together: this is because they are similar, and one of them has solution in the back of the book. Use the ones with solutions as examples to read and understand, and do the ones without solutions in the back.

For review of other sections, look through your homework, read your lectures and of course the textbook. A review sheet will be uploaded sometime this weekend.

There is no homework session this Tuesday, but I will hold extra office hours on Monday and Wednesday. If you want me to check your work, you can take a picture of your work and email it to me.

# Practice problems: limit proof

We have talked about convergence of sequences in class. In these proofs, you need to construct a N_{\epsilon} for an arbitrary \epsilon. Practice with these three problems: limit_problems
