Dear Students,

You have been sent an email from crowdmark with links to see your MAT237Y test 4 (you can see the test's statistics through Crowdmark). The test is out of 60, and the maximum possible score is 65/60, because Q3 was a bonus question worth 5 marks.

Crowdmark thinks the test is out of 65, but don't worry, we will keep track of this fact in the final calculation of the grades.

I uploaded a solution of the test to the course website: Test 4 Solutions

#### Past Tests

Posted: Monday, January 16, 11:46PM

Dear Students,

We have uploaded Test 3 from last year's course, in the "Notes and Uploads" section of the website.

(Update: please note that there is a missing absolute value sign in Q7 of last year's test. In the third bullet, there should be an absolute value around the partial derivative. Its absolute value should be less than or equal to 1.)

It is recommended that you use it as extra practice in preparation for this year's Test 3.

• Past tests' topics don't necessarily correspond in an exact manner to this year's test topics.
• For example, Q5 from last year's Test 3 (on the mean value theorem) is not a topic that is on this year's Test 3.

#### Test 3 Rooms

Posted: Monday, January 16, 11:40PM

Test 3 takes place this Friday Jan 20th, 5:10-7 pm.

The room assignments are:

• 1. Last Names: A-LU -> ES 1050
• 2. Last Names: LUO-WANG -> BA 1160
• 3. Last Names: WEI-Z -> MS 3154
• The early sitting takes place from 3.10-5 pm in BA 3008.

(The early sitting is only for students with a conflict who have registered with the coordinator).

#### Extra MAC Before Test 3

Posted: Sunday, January 15, 10:23PM

Dear Students,

The following documents have been posted related to MAC hours, in the "Notes and Uploads" section under "Office Hours".

• 1. The *new MAC Hours for the winter term*.
• 2. The Extra MAC Hours for the week leading up to Test 3.

Hope that you can make use of them!

#### Sufficiently Small Terminology

Posted: Saturday, January 14, 01:01PM

Dear Students,

The terms "big" and "small" refer to the magnitude of a number. For example saying that "a is sufficiently small" means that the "magnitude of a is small". That is, "a is close to 0".

For example, this applies to Q4 on Big List #11.

#### Supplementary Notes & Tests

Posted: Tuesday, January 10, 03:55PM

We have decided to make the supplementary notes recommended (but not required) reading material for students. Of course, you will still be responsible for any topics that are covered in Tyler's notes if there is overlap. For example, Optimization and Lagrange Multipliers are in the Tyler's notes.

This will apply to Test 3 as well, and I have edited the test announcement below to reflect the change.

I recommend that you still read the supplementary notes, as they elaborate on the topics, and will lead you to have a deeper understanding of the material, and hopefully to do better on the tests as a result.

#### Test 3 Material

Posted: Tuesday, January 10, 03:51PM

Test 3 will cover the following material:

• Tyler's course notes from sections 1.8(Uniform Continuity) 2.4, 2.5, 2.6 & 3.1.
• Your professor's notes from class on the topics of parametrizations (namely parametrizations of curves and surfaces, tangent vectors, spherical coordinates).

The exercises relevant to studying are:

• The big list problem sets #'s 8,9,10,11.
• (More practice can be found in the mini list problem sets #'s 8,9,10,11)
• Q#12 on Problem Set #5 (involves the concept of Uniform Continuity)
• Q#4 on Problem Set #7 (on Spherical Coordinates)
• The Extra "Potter" Problem Set 9.75 (On topic of Parametrizations and Uniform Continuity)

#### Mini Problems & Test 3

Posted: Tuesday, January 10, 03:30PM

Dear Students,

For Test 3, we do not guarantee to ask an exact problem from the Mini-List (or slight modification thereof), as we have been doing with the Big-List.

For future tests, however, we may choose to do this.

In other words, for future tests (i.e. Tests 4 & 5), "the rule of 25%" of the questions being slight modifications of the Big List will apply to the Big and Mini Lists together.

I still recommend you work on the Mini-List in your preparations for Test 3, as extra practice.

#### Potter Problem Set 9.75

Posted: Sunday, January 08, 12:03AM

Dear Students,

Last, but not least, please take a look at the "Potter Problem Set 9.75". It can be found under the "Notes" section of the course. It deals with the topics of "parametrizations and uniform continuity". It should be considered as an extra big list problem set.

Happy studying!

#### Supplementary Notes

Posted: Saturday, January 07, 11:58PM

Dear Students,

Yes, more exciting news for the second term! We have developed some supplementary notes on various topics. Take a look at the links in the "Notes" section of the course, under "Supplementary Notes".

Just like Tyler's Notes, these supplementary notes form part of the course, and therefore are required reading.

These are short, high-quality, expositions of some beautiful mathematics! I hope you enjoy reading them!

#### Mini List of Problems

Posted: Saturday, January 07, 11:51PM

Dear Students,

Students have spoken about wanting more practice problems. We are introducing a "Mini List of Problems".

They can be found under the "Notes" section of the course.

For each "Big List", there will be a corresponding "Mini List". I envision that these problems will be very useful, particularly (but not exclusively) for practice for the final exam.

I expect these problems to contribute to an enriching learning experience!

#### Problem Set 11

Posted: Sunday, January 01, 07:55PM

Problem Set 11 has been posted.

#### Winter Term Rooms
