# (Math 253)Practice test

Hi all,

Here is the practice test prac_test_1

Please note, this is just to help you get familiar with the format and content of the actual test, the test on Wednesday will NOT be the same test with different numbers. To review for the test, do the review problems assigned, review your self-diagnose quizzes and come to discuss any questions you have in office hours!

Key will not be posted, but if you can show me your work, I will be happy to check your work for you!

# (Math 152)Practice test

Hi all,

Here is the practice test prac_test_1 to help you get familiar with the format of the test on Wednesday.

The practice test is just to help you understand the length, rough content of the test. The actual test on Wednesday is NOT going to be the same test with different numbers.

Key will not be posted, these are all problems from your homework/lecture/self-diagnose quiz. Do feel free to check your work with me, either in office hours or email me a photo of your work.

# Coffee mugs and donuts are the same thing!

Hi all,

For some reason we talked about homeomorphisms during office hours today. For a mathematician, a coffee mug and a donut are exactly the same thing (topologically speaking only!). Don’t necessarily expect food if they tell you they brought donuts!

# (Math 253)Homework 4(Due 3/11)

Hi all,

Here is the set of problems due next Friday. You will notice problems from all sections we have covered so far, and this is because these are problems to help you review and prep for the test next week. So although they are due after the test, you should really do them soon and get help on them!

12.1: 8,12,14,28

12.2: 9,13,15,19,23

12.3: 3,7,23(if two vectors $\vec{u}$ and $\vec{v}$ are parallel, you can check if there is some scalar $c$ such that $\vec{u}$=$c \vec{v}$),38,39

12.4: 33

12.5: 5,6,13
