how do i do #22

Is that last row supposed to have the 1 on the left? This summarizes the determinants of elementary functions. I just looked at the proofs for these in my lin alg notes from a couple of years ago and they're really quite tedious...

Oops i wrote it wrong yeah a31 is supposed to be 1

 

So its pretty much -1 bc you have to switch the rows right?

do you find the determinant of elementary matrices by multiplying the diagonal altogether or is there more to it

 

im trying to look at my book and the theorem makes no sense to me

 

 

like this 

0 0 0 1 | 

0 1 0 0 |                  

0 0 1 0 | 

0 0 0 1 |

like why is dete(a) = -1

1 0 0 | 

0 3 0 |                  

0 0 2 | 

 

^would this be a upper and lower matrix or no?

me and my friends got different answers. i said it was both and they said it was neither bc it was diagonal. someone explain to me why pls

How do you do this im having a hard time doing it

And i don't know what identities (is that what you call them?) needed to do this

 

Like i know (AB)^-1AB = I and thats it im so dumb lol

can someone give me an example of evidence of evolution in terms of physical science?

 

idk would the environment changing be considered as evidence? i have no clue 

You skipped a step which would have made it a lot easier to solve without all the tricky numbers—look again at your last augmented matrix and you'll see that Row2Column2 is still -1 and you skipped dividing it by -1 to obtain the 1 necessary for the reduced row echelon form and instead went on ahead to Row3Column2. 

 

Here is the solved one btw if you want it (sorry if it's a bit messy lol):

 

 

omg i totally forgot that you could simplify and multiply by -1 im dumb lol

btw how do you find the answer by gaussian elimination? is it just like guess and check since gauss-jordan is reduced row? if i made any sense 

 

well actually

isn't reduced row (gauss-jordan) considered row echelon (gaussian) anyways? so the process is the same right? i don't make any sense at all im so sorry lol

someone help with gauss-jordan elimination

I DON'T UNDERSTAND WHAT IM DOING WRONG the numbers are so big there must be a simpler way to do this

the topic is understandable enough but doing it is ehhh

 

the first matrix is the linear system

THANK YOU

 

 

listened to brent faiyaz then stumbled upon this gem

the hook makes me feel all types of ways i love it lol

what do you guys think

berkenstocks are so ugly

how can you allow that abomination to be on your feet

 

and not only that

why is that shit so expensive??? $100 for dad shoes?? plus the sole of the shoe is made of cork THE FUCK 

they're not even for hiking so this doesn't excuse its ugliness

 

y'all need eyes if you like birkenstocks

just imagine e sens right now

 

he's probably like celebrating now that this "druggy" title has been pushed onto top lmfao

listened to sampha's debut album 

what a bop. i've been playing the album nonstop today; every song is so good

 

and this song

kali man

Brent fast becoming one of my fav voices too. Sonder's Into You is a good shout for top 10 projects of the year so far. Too Fast is definitely one of my personal fav songs of the year, the mv for it is incredible too. Not sure if I posted it yet so here:

 

 

 

Looking forward to hearing more from him, such an exciting artist.

that album was amazing and it sounds insanely pretty omg

searchin' is one of my faves and i loveeee the last part of too fast it adds so much dimension to the song

 

btw is brent faiyaz and sonder like the same person or a team or... i can't tell the difference lol

brent faiyaz is becoming one of my fave rnb artists omg this song is so good 

13 reasons why is like the better production valued version of unfriended

 

i don't get the hype

is the mean value theorem (for derivatives) pretty much like the definition of a derivative but adding that all points must be differentiable and continuous for it to apply?

ive been watching kdramas for a good 4 or 5 years and each year i realize how much i don't like kdramas. 

they've for sure gotten better but they still suck ASS.

 

at first they reel you in and you're addicted for a good 5-6 episodes but then the writers are like fuck this and completely change the character or story.

 

plus it doesnt add to the fact that sometimes their acting is so bad. you'll only see a handful of genuinely good actors and actresses while the newbie idol actors think that crying is scrunching their faces w/ no tears streaming down.

 

i just recently got into american shows and i realize why i like them.

they actually have conviction in the storytelling. they don't fuck things up last minute. the acting isnt particularly amazing but at least im decently convinced at their characters and invested in the stories.

Can someone please just tell me if this is a thesis statement? 

"The pursuit of an internal desire can have profound external consequences."

 

I'm not sure if it is too literal (as in it can't be 'argued' because it does happen in my texts). Is it conceptual enough, and if not, how can I make it conceptual? 

 

Thank you so much~

in my opinion, it's a very weak thesis.

a thesis statement should state your standpoint but also include your claims while keeping it vague enough to be explained in your paragraphs

 

ex.

"The pursuit of an internal desire can have profound external consequences in ways such as increased exuded pheromones, sexual tension, and aching joints" <-- I'm assuming this is supposed to be a informative essay

(tho if you wanted to use this, it has to have parallel structure. I just made it up on the spot. lol)

 

it's always safe to do 3 claims because most teachers require a 5 paragraph essay

what is the answer to this? limits can still exist at holes right, so is the answer I and II?

Here is the formula for the error of a Taylor series: http://www.dummies.com/education/math/calculus/calculating-error-bounds-for-taylor-polynomials/

i dont think there is going to be a calculator portion for my upcoming test.

is there a way to do this without calculator? i don't think my teacher said anything about a formula either

is error bound pretty much finding the next term that's not given or the last one given in the series?

 

e.g. if it's asking for the 3rd degree polynomial series for ln(1.3), do you find the 4th one to find your error bound?

can someone help me revise my expository essay on the american dream?

pls

if f(x) = sqrt(16 - 4x²)

isn't it just f(2) minus f(0)

it's indeterminate at 2 so you can't solve it that way

only through trig substitution or improper integrals but i still don't get the process

 

 

and how do you solve improper integrals? idgi
