# Math 151 hwk (Due 11/21)

Hi all,

Now that we are dealing with more complicated functions with more rules. Remember that we use these rules to break down a function into pieces that are easy to handle. Easy pieces might mean elementary functions (power, exponential, trig, etc.), or products and quotients of them. Try to study the functions (even simplify!) when given a problem to find the most appropriate rules to use. There are often more than one ways of doing these problems.

Problems to turn in:

3.4: 1-6, 8, 9, 11, 12, 17, 36, 49, 52, 53, 61, 62, 72, 80, 84, 85

3.5: 3, 4, 12, 21, 32

# Math151: Hwk(due 11/7)

Hi all,

Please start reviewing for the upcoming test and making your sheet. Note that you might want to have some properties for functions on your sheet. We will cover product and quotient rule on Tuesday and you should then be able to do these problems.

Here are some problems to turn in:

3.2: 1,2,4,6,9,12,19,20,28,32,43

3.3: 2,3,5,6,22,23,31,35

3.6: 2,5,6,9,34. Compare problems 5 and 6, be careful with the differences.

# Math 151 Hwk (due 10/31)

Hi all,

As we discussed in class, homework due 10/31 will be the worksheets on

1. Power rules and linearity

2. Exponential and log functions

3. Trig functions

Worksheet on trig function will be handed out on Tuesday and we will answer questions on these worksheets on Thursday if we have time.

# Math 151: limit of sin x/x as x approaches to 0

Hi all,

We used a fact last Thursday that $\lim_{x\to 0}\frac{\sin x}{x}=1$, and I didn’t explain why. Here is a rough proof of the fact for your own interest (from Dr. Andrew Loveless).

# Math 151(Practice test)

Here is a practice for the test: 151_Test_1P

I will be gone next week, so I will make myself as available as possible this week! Do not hesitate to make appointments with me to get help on these problems!

# Math 151:HWK 3(DUE 10/3)

Please review what we have covered for upcoming test!

I will go over the two problems in section 2.6 on Tuesday before you hand in the homework.

Hand in these problems on review day:

# How to study math?

According to Paul Halmos (image from here):

Don’t just read it; fight it! Ask your own questions,
look for your own examples, discover your own proofs.
Is the hypothesis necessary? Is the converse true?
What happens in the classical special case? What
about the degenerate cases? Where does the proof
use the hypothesis?

— Paul R. Halmos
