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

4. hba

Hmm :/ So where do i start ?

@ParthKohli

7. hba

@hartnn can you help ?

8. oldrin.bataku

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

9. ParthKohli

10. hartnn

Matrices is easier.

11. hartnn

can you evaluate determinants ?

12. ParthKohli

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

13. hba

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

14. hba

Hmm @ParthKohli

15. hartnn

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

16. hba

R1=R1+R2 ?

17. hba

No i am not sure about that :/

18. hartnn

19. hba

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

20. hartnn

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

21. hba

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

22. oldrin.bataku

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.

23. hartnn

and don't worry, its not difficult.

24. 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 ?

25. oldrin.bataku

@hba do you have a solid understanding of proofs?

26. hartnn

you don't know anything about vectors ??

27. hba

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

28. hartnn

revise it properly...

29. 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 :)

30. hba

So Matrices,Determinants,Vectors ? What else ?

31. hba

32. hartnn

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

33. hba

34. Callisto

I know it's not going to be helpful http://ocw.mit.edu/courses/mathematics/18-06sc-linear-algebra-fall-2011/Syllabus/

35. hba

Thanks a lot @Callisto

36. hba

@hartnn I wanna know about Fourier series ?

37. Callisto

Fourier tranforms is in unit III

38. hba

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

39. hba

I will just review the MIT OCW Vids :)

40. waterineyes

@hba

41. waterineyes

Is @hba here??

42. 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.

43. Callisto

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/

44. hba

@experimentX Thanks a lot :)

45. waterineyes

If you want to learn Linear Algebra, then check this link: http://openstudy.com/updates/50e55ef2e4b028291d752120

46. hba

Sure i will thankyou everyone.

47. waterineyes

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

48. hba

@waterineyes Staahp it.

49. waterineyes

Ha ha ha..

50. waterineyes

Liked or not??

51. 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

52. waterineyes

And I am not typing.. @hartnn

53. waterineyes

Ha ha ha..

54. waterineyes

Just kidding @hba ..

55. hba

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

56. hba

?
