Good enough!

Alec Fredericks

03:42

sounds great

Alec Fredericks

04:08

Yeah! I can hear you perfectly!

Brendan Mitchell

Devin Bowman

13:26

What sections will the test be covering, and where can we view this recording after?

Daniel Olvera

13:26

if you guys compare b of 2 to b of 3

Daniel Olvera

13:36

you find out that the function is not always decreasing

Callie Lunt

13:43

What helped me was to write out the first five terms, then I could see that the terms are not strictly decreasing. (This is for 49)

Blake Folsom

15:11

ohh ok did you make a combined function with both?

Daniel Olvera

15:30

no just do it independtly

Daniel Olvera

15:36

I don't know how to spell lol

Jacob Winters

15:42

Divergence test

Blake Folsom

15:49

ahh ok thanks

Caleb Hamblin

estimating error for sure

Jackson Small

16:13

Recognizing which test to use

Christine Lastra

16:47

also improper integrals (especially type 2, i find those kind of confusing)

desiree campbell

18:13

are we allowed to use our notes on the exam? no right

McKenzie Leininger

18:19

no

Alec Fredericks

18:23

we arent

Jaron Hamblin

18:26

yeah no notes or calculator

Jillian

18:28

no notes, no book, no calculators

Jacob Anderson

18:36

no proctorio

Andrew Bowden

u sub

Jerem Porter

20:09

u sub

Jennah Grant

20:36

is it only blurry for me?

McKenzie Leininger

20:44

Blurry for me

Merrill Redfearn

20:44

no

Aishwarya Ramesh

20:47

no

Drew Moss

20:50

it goes in and out of focus

Amy Walkenhorst

20:52

it is for me too

Jillian

20:56

the camera can't tell where to focus, it's getting there

desiree campbell

21:02

yeah same as drew moss haha

Jennah Grant

23:33

its still blurry

Michael Croxall

23:49

It looks good to me

Braxton Fjeldsted

23:52

Its definitely better

Sarah Stanley

24:01

Could you try turning your camera focus to manual and just have it focus on the board?

Tanner Frahm

25:00

Ok I missed it, why didn’t he just do u sub

Landon McNeil

25:09

he will next

Devin Bowman

25:15

^^ Yeah, doesn't it work if cos^5 = u?

Emily

25:27

^

Jillian

25:29

nah, you'd have a left out sin x

Mason Pilling

25:48

you could probably figure it out that way but it would be real messy

Mason Pilling

25:55

this way is a lot easier

Victoria Moreno

25:55

the u sub would be sin(x)=u, so cos(x)=du. then it would be the integral of u^4du

Isaac Hales

25:56

u=cos(x)^5

Isaac Hales

26:09

du=5(cos^4)*-sin(x)

Brandon Todd

26:34

When you take the derivative of u, you still have cos left in your answer which would make it a little more tricky.

Braxton Fjeldsted

30:28

But yeah the j is very distinct

Braxton Fjeldsted

30:35

Oops wrong chat sorry

Devin Bowman

31:15

Problem with integration by parts is that both v and u will be trig functions

McKenzie Leininger

33:00

There’s a list on canvas

Nicolas Onstott

33:02

there is a sheet on canvas

Ryan Ogden

33:10

these are them

Ryan Ogden

33:34

this is from dr. hughes

Jillian

33:43

not everyone has access to that page's materials

Jillian

34:02

access is denied to me, for example, probably because my teacher is Dr. Williams

Samuel Reynolds

34:21

I don't think Prof Andersen has a sheet like that for us

Braxton Fjeldsted

35:00

https://byu.instructure.com/courses/8397/files/2225169/download?download_frd=1 - does this work?

Mason Pilling

35:15

nope :(

Jillian

35:26

no, same access problem

Ryan Ogden

35:44

If I could pass files/screenshots, I would :(

Nicolas Onstott

36:04

put it in a google doc or something and just get a link

How is cos2x become sin2x/2

Andrew Bowden

38:17

does*

Christine Lastra

38:25

do we not need like, the double angle formula or sum

Devin Bowman

38:26

It's the antiderivitive

McKenzie Leininger

38:38

The power rule: cos(2x) * derivative of 2x

McKenzie Leininger

38:54

So antiderivative of that would be cos(2x)/2

Drew Moss

39:24

thx! @jacob

Jacob Gehrett

39:36

:)

Emily

40:02

you're my hero jacob

Heidi Hunter

40:16

just pull out your constants

Sean Humpherys

40:18

You could do a u sub on that part if you want

Jacob Gehrett

40:41

lol

Jacob Winters

what kind of sandwich?

Andrew Bowden

does anyone know if this review will be posted?

Sean Humpherys

44:35

It's secretly just two bread slices, Brendan ran out of money for condiments

Sam Wright

Yes it will

Sam Wright

44:47

cool thx

inverse trig hammers me

Samuel Reynolds

54:19

itll show up as a webassign assignment

Sean Humpherys

test is on webassign

Merrill Redfearn

54:25

Arctan gets me too

Mason Pilling

54:26

trig is kinda just the worst

Samuel Reynolds

54:28

but don't click on it until youre ready to begin cause the clock will start ticking

Matt Parry

54:35

ok thanks!

Sean Humpherys

54:56

Trig isn't bad if you have a formula sheet on hand. Remembering stuff is the problem

Adam Norton

55:07

Facts

Jacob Anderson

55:10

true dat

Joshua Culmer

55:36

True, gotta just memorize the sheet

Wendell Loh

55:52

yeah because i'll remember it once the test is over

Chandler Jensen

56:58

This site has some fun songs to help remember calculus stuff (#21 is helpful to remember the derivative of arctan): https://icanhasmath.bandcamp.com/album/calculus-the-musical-3rd-edition

Dylan Skinner

57:40

what did she say?

Aishwarya Ramesh

58:34

integral of tan x is - ln|cosu| + c

yeah honestly just a list and what order to use them would be awesome

Sarah Stanley

^^^

Jacob Anderson

01:00:46

^^^^^^^^^^^^^^

Jillian

01:01:08

hang on, Dr. Williams made one, I'll see if I can post a link here

Noah Housley

01:01:08

its more like a tool box then a list...I don't think there's a priority of which one to use, I think its just recognizing patterns and using the right tool for the right pattern.

Carter Reeves

01:01:11

cause i lost in the shear amount of test haha

Noah Housley

01:01:18

that being said...I'm not that great at it haha

Braxton Fjeldsted

01:01:32

What order to use them is just personal preference and the stuff Noah said

Jacob Anderson

01:01:54

Is it just me or can I only see exam 1?

Ben Woodland

01:02:00

I can’t see the exact question on my screen is that happening to anyone else

Brielle Anderson

01:02:05

same

Sam Wright

01:04:40

where can we find all of the practice tests?

Sam Wright

01:04:56

does it depend on the teacher? I don’t see on canvas where to find it

Caleb Calderwood

01:04:56

Jacob Anderson

01:05:08

At the top of the module page in learning suite/canvas

Joshua Culmer

01:05:25

@caleb, you barely beat me to it

Sam Wright

01:05:28

thanks

Caleb Calderwood

01:05:43

I already had it copied lol

Ryan Johnson

01:06:00

limit comparixon

Nicolas Onstott

01:06:38

the 1 just doesn't really matter compared to infinity so you can just take it out

Sean Humpherys

01:06:42

Why aren't you just taking the limit

Jillian

01:07:58

https://docs.google.com/presentation/d/1_j8DdpSpTUQSNOmg7nxkgnFaZaJMJyikFmYO6VYGfSE/edit?usp=sharing A copy of Dr. William's handy chart for convergence tests

try again, just changed it, sorry

Kent William Allen

01:08:56

Thanks!

Brandon Todd

01:09:38

So there are different p-rules for type 1 and type 2?

Ben Woodland

01:09:44

Why does that top one diverge? Does the p rule change?

Devin Bowman

01:09:47

p is the highest coefficient values for the numerator and denominator?

Jaron Hamblin

01:10:23

because the p -series basically switches because of the type

Ben Woodland

01:11:12

So for type 2 p<1 makes it converge

Thomas Witney

01:11:28

yes

Braxton Fjeldsted

01:11:29

indeed

Ben Woodland

01:11:36

Alrighty thank you

Jaron Hamblin

01:12:04

yep and p greater than and equal to 1 is divergent

Jaron Hamblin

01:12:12

for type 2

Jacob Winters

01:14:40

the divergence test only tells us if the expression diverges, not if it converges

Noah Housley

01:15:34

pretty sure the tests only apply to series..with integrals I think you just take the limit as x goes to infinity

Devin Bowman

01:16:09

a bit worried that all these example problems involve trig...

Jaron Hamblin

01:16:50

same

Sam Mildenstein

01:19:00

We’re all gonna be TRIGgered come test time...

Daniel Olvera

01:19:09

lol

Thomas Witney

01:19:17

yeah im already at my LIMIT

Chandler Jensen

Andrew Bowden

01:19:29

Im honestly really worries

Aishwarya Ramesh

01:19:36

same

Daniel Olvera

01:19:38

but guys this test is INTEGRAL to our grades

Jacob Anderson

01:19:42

I’m really worries too

Blake Elzinga

01:19:45

don't stop beleeeeving

Dallan Adamson

01:19:47

maybe if we all fail the math dept will give us free points

Wendell Loh

01:19:53

there's an idea

Sam Mildenstein

01:19:53

^^

Blake Elzinga

01:19:54

just hold on to that feeeeling

Jacob Anderson

01:19:58

bet

Chandler Jensen

01:19:58

let's make a pact to all bomb the test

Dallan Adamson

01:20:04

down

Sam Mildenstein

01:20:09

I hope nobody cheats they’ll ruin our fail curve

Noah Housley

01:20:11

I'd only fail for money

Daniel Olvera

01:20:13

i don't even need to make a pact to fail

Dallan Adamson

01:20:21

Noah, I can provide that

Jacob Anderson

01:20:21

Ill give you 2 monopoly money

Dallan Adamson

I've got $6

Noah Housley

01:20:45

you don't have that kind of monehy

Merrill Redfearn

01:20:46

This class is a SERIES of headaches

Jackson Small

01:20:50

You got Venmo?

Braxton Fjeldsted

01:21:11

Or a used high five

Noah Housley

01:21:14

….wo....a monopoly game with venmo….that's my next date

Ramya

01:21:16

hahah

Heidi Hunter

01:22:19

wait how did the upper bound change from pi/2 to 1

Ryan

01:22:33

he plugged it into u

Cal Hargis

01:22:38

This class gon put me in a mental’hospital

Thomas Witney

01:22:44

it was plugged into sin0, or u

Jaron Hamblin

01:22:48

you have to change the bounds based on the u sub

Heidi Hunter

01:22:49

gotcha

Samuel Reynolds

01:22:49

Thx guys 😂😂😭

Spencer Fairchild

Ben Woodland

01:23:38

Ya Brandon you could

Thomas Witney

01:23:41

lol good one

Ryan

01:23:56

would graders take off points if we do what brandon said?

Ramya

01:24:05

I do not think he is looking at the chat so if you have a question you might want to say what your question is.

Sam Mildenstein

01:24:07

L’hospitals totally rule

McKenzie Leininger

01:24:25

Well on that test you don’t have to upload any pictures or anything I don’t think

Brenden Nuttall

01:24:25

I'm sure they wouldn't @Ryan, you'd get the same answer

Adam Norton

01:24:27

So if our test is gonna be on web assign will it be auto graded or by hand?

Andrew Bowden

01:24:32

Its multiple choice so its all or nothing

Braxton Fjeldsted

01:24:43

Someone is unmuted I think

Andra McKell

01:24:46

no there is some written questions

Adam Norton

01:24:47

So why are we saying “the graders” like this and that

Ramya

01:24:48

is it all multiple choice

Jillian

01:24:51

some are not multiple choice I thought

Andra McKell

01:24:52

aer*

Braxton Fjeldsted

01:24:52

Not all

Samuel Reynolds

01:24:54

some of it is multiple choice but some of it is also written like we write in for HW

Nicolas Onstott

01:24:57

lake mute yourself

Samuel Reynolds

01:25:00

but we wont know our score until the test closes

Nicolas Onstott

01:25:01

blake

abby

01:25:03

Blake mute

Ryan Ogden

01:25:03

mute please

Adam Norton

01:25:06

Okay that makes sense

Jaron Hamblin

01:25:28

how many questions are on the test?

Braxton Fjeldsted

01:25:36

yeah

Ramya

01:25:37

but we turn in written hw on a gradescope

Devin Bowman

01:25:44

Series is summation of sequence?

Brielle Anderson

01:25:45

I think it's also fill in the blank....not just multiple choice. It has the same set up as the homework. Anything we can do on the homework on webassign could be on the test

Samuel Reynolds

01:25:51

i mean it is like when we entire in fill in the blanks in WA

Samuel Reynolds

01:25:53

since the test is on WA

McKenzie Leininger

01:25:54

Yeah our prof said it’s MC and fill in blank

McKenzie Leininger

01:25:55

No pic upload

Sam Mildenstein

01:25:56

So do we get instant feedback per problem, or does it just tell us what our final score is after submission?

Samuel Reynolds

01:26:03

so some will be MC and others will be just like WA HW

Nicolas Onstott

01:26:07

no instant feedback

Sam Mildenstein

01:26:11

great

Riley Isom

01:26:12

Hey I’m sure this has already been answered, but will this be recorded and posted on canvas?

Samuel Reynolds

01:26:12

^^^

Braxton Fjeldsted

01:26:19

Can’t fail the test if you don’t take it - 200 iq moves

Samuel Reynolds

01:26:25

its being recorded and should be posted o the math lab website

Jillian

01:26:33

^^^

Jaron Hamblin

01:26:38

do we know how many questions the test is?

Ramya

01:26:45

13

Chandler Jensen

01:26:45

whats the math lab website?

Sean Humpherys

01:26:46

sequence is a bunch of dots

Braxton Fjeldsted

01:26:48

12 or 13

Adam Norton

01:26:52

I think it’s 13 yeah

Aishwarya Ramesh

01:26:56

5 more questions than the practice test

Victoria Moreno

01:26:56

i think my teacher said it's about 13 questions

Samuel Reynolds

01:26:59

the math lab website is the math lab website lol.

Jaron Hamblin

01:27:02

ok cool thanks

Samuel Reynolds

01:27:12

its where all the practice tests were linked

Samuel Reynolds

01:27:40

yeah since we have 3 tests in this class (and since its covid right now) i think the test should be like 15 questions or less

Braxton Fjeldsted

01:28:12

Converges if p is greater than one - this is the third time we have done this problem in my section lol

Jillian

01:28:19

math lab website with recording will be https://math.byu.edu/?page_id=193

Jacob Anderson

01:28:30

So glad he’s doing this one

Devin Bowman

01:30:22

so if it looks complicated, do an integral test first

Jillian

01:30:55

IF it's positive, decreasing, & continuos

Merrill Redfearn

01:31:14

^^ what Jillian said

Aishwarya Ramesh

01:32:31

wait if it is on webassign would we not get our score back right after

Samuel Reynolds

01:32:59

no

McKenzie Leininger

01:33:03

Normally yes but for cheating stuff I think they said it won’t show your score until everyone’s done

Samuel Reynolds

01:33:15

we have to wait until they test closes to get our scores so Friday at 12am we will knw

Samuel Reynolds

01:33:17

know*

Sam Mildenstein

01:33:36

There’s no class tomorrow, right?

Aishwarya Ramesh

01:33:43

we still have class

Ramya

01:33:45

there is class tom

the 10am class with Andersen is LIT

Blake Folsom

01:36:53

heck yeah it is!

Sean Humpherys

01:36:53

it is

Jaron Hamblin

01:37:05

totally agree

Ramya

01:37:15

I like the class but everything is due before then that's what I don't like

Carter Reeves

01:37:15

the prequel quotes for 30 mins were a *little* much haha

Jaron Hamblin

01:37:28

that was the best part yesterday

Jillian

01:37:36

really? Ours are due at midnight

Sam Bishop

01:37:40

nick goes hard in the muhflippin paint

Carter Reeves

01:37:43

Aishwarya Ramesh

01:38:17

webassign is due before midnight and written hw is due 15 mins before class

Samuel Reynolds

01:38:41

i just do the videos, the prequiz and the written HW the night before a MWF class

Adam Norton

01:38:46

As much as I need to keep studying I’m totally gonna go watch the debate

Samuel Reynolds

01:38:54

Bruh sammee

Samuel Reynolds

01:39:00

Gonna go watch Steven Crowder stream the debate

Thomas Witney

01:39:01

isn't it at 7

Jaron Hamblin

01:39:01

that's what I do since I usually wake up 10 mins before class

Ramya

01:39:12

same

Jaron Hamblin

01:40:11

the debate will be so great

Sam Bishop

01:40:17

i feel like i live in a dystopia and the presidential candidates exist only for my entertainment

Blake Folsom

01:40:38

hahaha same

Jaron Hamblin

01:40:43

thats what happens when both candidates are super old haha

Jillian

01:41:21

@Amy McDonald please mute

Ryan Ogden

01:41:40

@Brock Johnson please mute

Blake Folsom

01:42:21

freaking English in Math

Jacob Anderson

01:42:31

Should be an English major

Dallan Adamson

01:42:36

hahaha, they're testing us on both

Adam Norton

01:42:55

Okay I’m bouncin good luck everyone!

Andrew Bowden

01:43:29

So all convergent series approach 0?

Spencer Jorgensen

01:43:38

less than or equal sign right

Emily

01:44:09

yes Andrew, but not all series that approach 0 are convergent

Andrew Bowden

01:44:34

thanks

Jon DeAlba

01:44:42

Sorry, I just joined the class. Did he go over the last bullet point?

Jon DeAlba

01:44:51

Was it true or false and why?

Blake Folsom

01:45:12

no he didn't

Jon DeAlba

01:45:41

The one where it has a fraction = L > 1?

Ramya

01:45:49

I am hearing what he is saying but I am not comprehending anything

Ben Woodland

01:45:56

The last bullet point just shows that as the series goes on the terms grow in size, so since the series isn’t decreasing the terms will add up to be bigger and bigger and diverge

Alex Edwards

01:46:19

what Ben said;)

Jaron Hamblin

01:47:55

so the 3rd to last one is the false one

Jaron Hamblin

01:47:57

?

Victoria Moreno

01:48:05

yes

Jon DeAlba

01:49:23

I think the last one is the divergent one

Jon DeAlba

01:49:36

For question 7

Sean Humpherys

01:50:05

correct

Lance Parrish

01:52:09

I feel that

Jacob Anderson

01:52:19

lol

Bryce Marshall

01:53:13

Does anyone know when the exam closes

Jacob Gehrett

01:53:26

Midnight on Thursday I think

Kadyn Wright

01:53:28

Thursday at 11: 59 pm

Jaron Hamblin

01:53:29

Thursday at 11:59 pm

Bryce Marshall

01:53:34

thanks

Andreas Lehmann

01:54:48

Why doesn’t the third one diverge

Braxton Fjeldsted

01:55:09

Because the limit of the inner function goes to pi

Daniel Olvera

01:55:11

because the two n's cancel leaving the cos of pi which is a finite number

Andreas Lehmann

01:55:12

I thought a cos function has a nonexistent limit

Nicolas Onstott

01:55:17

because the power of n is the same? So the difference will be pi (roughly)

Andreas Lehmann

01:55:38

Oh ok cool

Landon McNeil

01:56:18

As n goes to infinity, arctan(n) goes to pi/2

Samuel Craven

01:56:24

arctan becomes a constant

Brandon Todd

01:58:18

could you also compare the last one to 2n^2/sqrt n^3 and compare it to 2/n^1/2 and p < 1 which diverges, so our original function is bigger so it will also diverge?

Nicolas Onstott

01:59:52

Could you do estimations please?

where will the recording be posted?

Jacob Gehrett

02:05:23

there I think

iPhone

02:05:45

awesome thank you, did he say when it would be put on there?

Jacob Winters

02:06:40

brilliant

Jacob Gehrett

02:07:02

I have no idea when it will be there :/

Jillian

02:07:21

they said it could be awhile....

Mason Pilling

02:07:47

its a two hour recording so my guess is itll take a while tp upload

Mason Pilling

02:07:57

i wouldn't expect it until tomorrow

Andrew Bowden

02:08:23

The error means the rest of the sum that we couldn’t add with the partial sum?

Braxton Fjeldsted

02:08:57

Guys make sure you’re muted

Brenden Nuttall

02:09:44

we're finding R_n, which is the maximum error for the partial sum s_n compared to s

Jaron Hamblin

02:11:14

ohhhh I totally get it thank you

McKenzie Leininger

02:13:39

Since the error is 3/4*100^4, then the series + error is greater than or equal to the actual value, which is greater than or equal to the series minus the error

McKenzie Leininger

02:13:40

I think

Takun Purba
