just so u know i sucked at linear algebra, no idea how i got an A lol

tht means u didn't....:P tht means ur talented :P

Oh it's that matrix multiplied n times...

hold on.. let me see if i can find anything

im trying to do this for general case... a,b,c,d

too bad only bahrom can help

ok..take ur time ^^

@Everyone if u want to help...feel free to do it

if n = odd it is the same matrix and if n = even it is the diagonal matrix

don't you diagonalize the matrix into A=SDS^(-1)
and then A^n= S D^n S^-1

i meant identity matrix (no just diagonal)

then even = matrix
and odd = same

*ident matrix

wait this is eigenvectors?

you alternate between A and I

wht is/are eigenvectors????????? O.o

|dw:1329490292192:dw|

lol good question, my prof never managed to cover that

@Nenad i don't get it at all :S

he's row reducing the matrix

nenand, can you do that in here and still have the same answer?

|dw:1329490445758:dw|

what's T?

angela is this from a textbook?

wht r these famous eigenvectors..this is the first time i've heard these...

my home-works :((((

I would like to know what are Eigenvectors & Eigenvalues ?

page no.16 :P

hahaha :D

OHHH phi LOL!

i feel stupid.. -_-

i should've just tried to multiply this actual product, not the freakin general abcd case..

ok how abt
|dw:1329491265305:dw|

that's also identity.. i think cuz u'll get Cos^2 and Sin^2..

if you know your trig identities
A*A gets you
[ cos 2x -sin2x ]
[ sin 2x cos 2x ]

oh yes i know...i had multiplied -sinx with cosx instead of sinx...
thanks :)

:O:O OMG!!! Can i have ur brain just for one semester pleaseeeee :(((((((

Lol angela

hahaha lol yea.. i feel the same way when it comes to certain problems lol

xD
