@forbidden: buy the usb hub at strathfield car radios. if you live near the kingsford one, im working there on sunday.
and LOL i have cod 4 and 5 both downloaded =)
cod4 is a fun/funny game (except on Veteran difficulty) it is an award winning game its fun to play this game with buddies sometimes during summer
urrggghh.... math1231 algebra class test tomorrow........
So i just need to confirm/find out how to find out some stuff:
Kernal: ?
Image: ?
Basis: Row reduce, then the number of leading columns?
Dimention: Same thing?
Rank: Same thing.
Nullity: Row reduce, then number of non-leading columns.
Here is my incorrect answers from my second attempt at online question:

4/10, i got 6/10 for first attempt, can someone tell me how to do the ones i got wrong? I at least wanna completely pwn the online tests, give me better chance of passing the course =)
If I have time I will post more.
Question 1
(Hint: you don't need to find all the eigenvalues and eigenvectors to answer this question)
^
Timesaver and a real WHOPEEEEEEEEEEEEEE
Anyway I'm pissed off with the forum's LaTeX functionality.
Multiply the 1st and 3rd row by the eigenvector and you get a resultant vector with 4 rows and 1 column.
(You can multiply using all rows if you are confused)
Compare the eigenvector (4 by 1) with the resultant vector (4 by 1 also)
eigenvector times lambda equals the resultant vector.
So solve for lambda! (It wasn't 3!!!)
Remember A
v=λ
v
Question 4
OH HELL NO it ain't the second choice.
There is a power in one of the variables (the squared).
Next time you see a power in one of the variables avoid it! It is NOT a linear transformation whatsoever!
4th one involving the dot products is also a bad choice.
I received a test question or something proving whether the dot product of two vectors are linear transformations or what not are linear transformations and they aren't apparently. I can't remember proving it.
So choice #1 and #3 seems to be the best choices for you.
They should be more specific with what they teach, this is linear algebra they are teaching not just algebra as a whole (including chaotic systems blah blah)

are you in the library?
look for me going on bos and looking up the M60 machine gun and other firearms and munitions on Wikipedia
