Linear algebra is about topology and vectors and stuff if I am not wrong.

Hmm :/
So where do i start ?

- hba

Maybe I should start with Vectors ?

- hba

@ParthKohli

- hba

@hartnn can you help ?

- anonymous

Less topology, more vector spaces and linear & affine transformations.

- ParthKohli

Yes, you should start with vectors.

- hartnn

Matrices is easier.

- hartnn

can you evaluate determinants ?

- ParthKohli

I guess I'd let hartnn do the thing :)

- hba

Well i learnt how to evaluate determinants two years ago,I think i know how to do that :)

- hba

Hmm @ParthKohli

- hartnn

what about transformations in rows and columns ?? like R1=R1+R2
R3=4*R3
and so on...

- hba

R1=R1+R2 ?

- hba

No i am not sure about that :/

- hartnn

|dw:1357226275174:dw|

- hba

Yeah i remember that :)
What is this equation btw ?
\[Ax=\lambda x\]

- hartnn

its used to find eigen values of matrix A.
called the characteristic equation.

- hba

Well the book says it is a key equation.
Anyways,What next @hartnn ?

- anonymous

Elementary row operations are rather insignificant here... you need them to do Gaussian elimination but linear algebra is a broader field than merely reducing matrices to row-echelon form.

- hartnn

and don't worry, its not difficult.

- hba

Well,I am gonna start with the course on 4th feb,so i am sorta worried because i heard it is difficult.
Do i need to know anymore things before hand @hartnn ?

- anonymous

@hba do you have a solid understanding of proofs?

- hartnn

you don't know anything about vectors ??

- hba

Well i had a whole chapter dedicated to vectors which i studied two years ago :)

- hartnn

revise it properly...

- hba

@oldrin.bataku I am just starting Uni.
So i am not sure what sorta proofs you are talking about
@hartnn Sure i will revise all of them again :)

- hba

So
Matrices,Determinants,Vectors ?
What else ?

- hba

What about linear transformations ?

- hartnn

go through math.mit.edu link , there you will find topics....

- hba

What about fourier series,Can you tell me about that ?

- Callisto

I know it's not going to be helpful

- hba

Thanks a lot @Callisto

- hba

@hartnn I wanna know about Fourier series ?

- Callisto

Fourier tranforms is in unit III

- hba

Oh thanks a lot
@Callisto @oldrin.bataku
and @hartnn

- hba

I will just review the MIT OCW Vids :)

- anonymous

@hba

- anonymous

Is @hba here??

- experimentX

for beginners this will be good material
http://tutorial.math.lamar.edu/Classes/LinAlg/LinAlg.aspx
MIT ocw focuses more on engineering, if you are interested in learning linear algebra i suggest you follow a good book.

- Callisto

Sorry I did something wrong, big thanks to @experimentX
Fourier series is in 18.03

- hba

@experimentX Thanks a lot :)

- hba

Sure i will thankyou everyone.

- anonymous

Ha ha ha ha..
I am seeing number of viewers seeing that link are increasing..

- hba

@waterineyes Staahp it.

- anonymous

Ha ha ha..

- anonymous

Liked or not??

- experimentX

here a list of them ... I am following Linear Algebra by Serge Lang
http://mathoverflow.net/questions/98338/can-anyone-recommand-a-good-textbook-for-self-learning-linear-algebra

- anonymous

And I am not typing.. @hartnn

- anonymous

Ha ha ha..

- anonymous

Just kidding @hba ..

- hba

It's fine.
@experimentX Should i follow the same book ?

- hba

?
