anybody feel like teaching me how to calculate the dimension of the null space of a matrix? or how to calculate and determine eigenvectors and eigenvalues? i hate college testing. tests are the only thing that count too, since there's no assignments, or any of that crap anymore. i don't know what the hell to do. i hate being a lazy idiot that wastes all his time on ns.com. gah...

I agree... I hate tests! i've been on ns and msn all night instead of studying for my zoo quiz and stats midterm. also just got my mark for a midterm i thought was super easy... i got 65. I don't know what's wrong, I'm working just as hard as I normally do but lately all my marks have been WAY lower than normal.

^ exact same here, i was about to make a thread on it... i study my ass off yet my grades are the worst they've been throughou my schooling life. My parents are going to flip shit in 2 weeks when report cards come out

skiing makes

me really

happy.

spreadin\' the love, y0
 
it's not the matricies, its the other big words

^ i know. that's what i mean. i learned these big words in gr.9. i'm supa smart.

i'm taking gr.12 math in gr10. and they said i can go to da university with my math and physics level

hmmm

Eigenvalues are from (lambdaI-Ax) and then eigenvectors are found by plugging the lambdas back into the matrix.

as in a 2 by 2: if Matrix A is say:

2 4

3 5

then you go

lambda - 2 -4

-3 lambda - 5

take the determinant

in this case:

(lambda - 2)*(lambda - 5) + 12.

Now i just used random numbers and this shit may get you complex eigenvalues and i dont know if you have dealt with that, but most likely you will get nice numbers that they have predetermined. Then you put those lambdas you solve for from the quadratic and put each one into the lambda matrix above. You then do row operations to get the identity and get your vectors out of that. I hope that helped. The vectors part probably didnt.

signatures are for pussies

 
^ holy..shit......do you feel like helping me out with some intergration? or even coming and writing my biology midterm for me....its at 930 tomorrow morning, and im a bit behind.....

and my motherfucking coffees motherfucking fucking cold

 
yea yea, i took that shit to last year. glad im done with it. gotta love cal and linear
