Integration by Substitution

[jyhj93]

i find this easy to masturbate to.

[mitchelisonfire]

a more simple approach is just taking the indefinite integral, then using the values to determine the definite integral. this way you don't need to change the values during the integration process.

[dimsuminab0x]

it's hard for me to concentrate on what she's talking about...she's just too cute...I need to find another video

[AunShovah]

I'd like to bend her over a barrel and show her the 50 states

[Mrjammintime1]

wth people, show the math instructor some respect.

[lillibeth13]

I don't see the point in changing the limits of integration when using u-substitution. All you need to do is find the INdefinite integral and evaluate it at a and b, your ORIGINAL limits of integration.

[BANANAENDMANDARINA]

Are you a proffesor???' Cause I would like to be in that class.....for sure.....yes i would....

[BigBeansBalli]

i've just experienced a growth rate around my one on twos

[AznS0ulja]

she can expand my brackets and derive me. I'll make sure that I'll be a multiple root for her

[Quarker99]

Wow, those are a beautiful pair of limits on that integral...

[neel1393]

Interesting video, if I had a teacher like that... :D

[tracy610czy]

@neel1393 if u have , u cant study

[neel1393]

@tracy610czy Well, I could study human anatomy for sure from her then. :D

[il1029]

Why wasn't she my math teacher?????

[juanpedro19840914]

ok.. now topless, please..!

[kindom2010]

Damn it!! I cannot concentrate well!!

[jay1wo]

Who is she and where can I find more of her video?!!

[oheycoolkid]

ok! 

[fjbutch]

I didn't have a clue what I was watching, but it was impressive anyway...

[0nikage781]

my brain imploded.

[snobad]

FUCK ME PLZ

[nobodygetsmyusername]

@snobad

fuck off pervert

[DrLasker1]

Damn, I'd like to lay a tangent to those curves.

[JoeMakesCoasters]

@DrLasker1 lol!

[TroyaE117]

It is sometimes better not to use the changed limits for u.

Integrate the expression using the substitution to give the integral in terms of x....

(2/3)*(1-x)^(3/2) - 2*(1-x)^(1/2)

...and use your limits for x from 0 to 3/4

The answer is the same... 5/12

Good tutorial.

[b00sh]

My brain just exploded.

[gaussiann]

@Rizmaestro

nope, 5/12 is correct

[Rizmaestro]

never mind, i know where i went wrong.

I paid attention.

[uchihasasuke7777]

I remember doing this question lol. Almost 3 years later now I have no idea how to work out these things... Uni can do that.

[larvitar0riproot]

@kalyan3 She's doing a question from the 2007 HSC. So, it's probably safe to say that not only is she Australian but she's also a New South Welshwoman.

[DeamonSun]

Interesting. Never knew you could flip the numbers with the negative outside.

[fetzkochl]

lol i really learned something by this :D

[WaROdin]

I got minus 5/12 when i did it. am i the only one try to learn productively off this video?

[joshmdmd]

@WaROdin you can see when she brings the negative outside of the integral she then removes it by flipping the bounds.

[browno26]

wait what 

[romyboy]

my answer is -5/12 :(

[barbados496]

mam their is mistake in your question.........!

[ijazlsaz]

Nice Girl

[lena11sandy]

wat a nerd lol i can't evn do year 7 maths let along this

[samsaras]

no need to do these steps. you can simply use a graphing calculator to find the area if your syllabus allows it.

[fobla]

freakkk i just finished this stuff!!!! i hate it soo much!

[lyounamu]

too easy.

[poisonadded]

wow i am starting to love math..lol!!!

[zal159]

Now i understand...haiz.. maths so hard

[devilboy55]

Wish I had her as my math teacher.

[digity1990]

yer that was ext 1 i do that

[nuktu]

I love that accent!
