Hey chit-chat thread

I was wondering what societies in UNSW are awesome?

And also can someone plz tell me what is involved in being a member of the Athiest Society (like what they get up to and stuff)

Thks...much appreciated

 

[Omie Jay]

Take your pick:
Clubs List - OWiki

...maybe give me positive rep for being so helpful

 

[Omie Jay]

Also, to all prospective future unsw students and 'give-me-help-because-i-do-not-know-where-to-find-this-info' people, for the above enquiry i typed into google search: "unsw societies", and the first link i got was the one i posted up.

GOOGLE IS YOUR FRIEND!!!

 

[uhawww]

Is it just me or is that wiki really buggy? I really need to edit a page but it's not letting me login or anything... :\

 

[Omie Jay]

dunno, it had the info so i posted it up, didnt notice anything that needed fixing.. maybe it is buggy.

For some extra sexy time?

If it were for that, I'd long have a double bed. I have 2 beds because my sister sometimes comes back from boarding school and sometimes sleeps in my room.

Anyway, I'm off for a vacation overseas for the next 2 weeks so I won't be around as much (if ever). See you all when I get back.

 

[uhawww]

He didn't tell us where he's going... now I'm curious for the next 2 weeks.... :angry:

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 =)

@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

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 Av=λv

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)









Omie Jay

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

 

[Omie Jay]

Haha, nah im home. If i was at the library, i'd have my laptop with me, and i'd be downloading assassins creed directors cut, and wanted.

With first question, why do u choose the 1st and 3rd rows? How do u come to that conclusion?

lol dling??
the IT department did warn students about copyright infringing shit flowing around here and there.m

the second row is meaningless. there is a zero.
zero times anything equals zero.
wont get an eigenvalue out of that.

i omit the fourth row to save time.

remember the hint they gave you.

 

[Omie Jay]

k thanks.

grrrrrr needs to learn, i hate being so lazy. And this weather isnt really helping either.....

wtf does "Find the basis for the kernel of A" mean? (given a matrix A)

/ 1 2 3 1 2 \
| 3 5 8 5 5 |
\ 1 3 4 -2 4 /

Kernel (matrix) - Wikipedia, the free encyclopedia

so it's basically the linearly independent vectors that you can use to make the matrix A

 

[Omie Jay]

k thanks, +rep.

omggg woah when did bos update their profile page interface?!?! haha. im gonna go check mine out and try to snazz it up if bothered!
