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
  • hba
@hartnn can you help ?
Less topology, more vector spaces and linear & affine transformations.
Yes, you should start with vectors.
Matrices is easier.
can you evaluate determinants ?
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
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 :/
|dw:1357226275174:dw|
  • hba
Yeah i remember that :) What is this equation btw ? \[Ax=\lambda x\]
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 ?
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.
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 ?
@hba do you have a solid understanding of proofs?
you don't know anything about vectors ??
  • hba
Well i had a whole chapter dedicated to vectors which i studied two years ago :)
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 ?
go through math.mit.edu link , there you will find topics....
  • hba
What about fourier series,Can you tell me about that ?
I know it's not going to be helpful http://ocw.mit.edu/courses/mathematics/18-06sc-linear-algebra-fall-2011/Syllabus/
  • hba
Thanks a lot @Callisto
  • hba
@hartnn I wanna know about Fourier series ?
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 :)
Is @hba here??
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.
Sorry I did something wrong, big thanks to @experimentX Fourier series is in 18.03 http://ocw.mit.edu/courses/mathematics/18-03sc-differential-equations-fall-2011/unit-iii-fourier-series-and-laplace-transform/fourier-series-basics/
  • hba
@experimentX Thanks a lot :)

  • hba
Sure i will thankyou everyone.
Ha ha ha ha.. I am seeing number of viewers seeing that link are increasing..
  • hba
@waterineyes Staahp it.
Ha ha ha..
Liked or not??
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
And I am not typing.. @hartnn
Ha ha ha..
Just kidding @hba ..
  • hba
It's fine. @experimentX Should i follow the same book ?
  • hba
?
