Hello,

anyone doing math133, could u please tell me how far we got into Differential equations? All of chapter 15 and 16 of chen notes or just parts?


Thanks

Unfortunately i can't help you, but it would have been hilarious if you change the title to
MATH133 - Last Minute Help

lol, it would been the 3rd thread like it

 

[bigredboof]

Also, about interpolation. Do we need to know the following:

- minimax approx
- least squares approx
- Newton Difference tables

Are these going ot be on the exam?

Thanks

all of chaps 15 and 16 - thats ALL differential (dw, it ain't that bad...)
for interpolation, methinks we just have to know the Newton's method and the Lagrange method, nothing else. That chapter on interpolation was crap.

side note: algebra is tying my brain in twisted little knots. yes. yes it is.

Thanks heaps for your help mini.

yeah interpolation is shocking. Im glad you told me its just Lagrange and Newton!!

I agree with you on the algebra part. I have no idea on all that vector stuff and group theory!!!

lol, np, glad i could help

good luck in ur exam

time to ressurect this thread

what chapters are relevant from Chen's piece of crap notes?

Hello,

Can someone please help who has done the 2003 past paper.
In Q2 part a part II) it says to find an invertible matrix and diagonal matrix..... however the eigenvalues are 0,1,-1, and according to my notes, a matrix is not invertible if their is an eigenvalue = 0

Can somebody please help

Thanks

hrm...
all i can remember is how to invert a 2x2 matrix...sry 4gotten how to do bigger ones.

ask flyn' he does combined maths he'd prolly know

 

[flyin']

flyin' can't remember such things. haven't done any maths for a whole semester.

 

[toknblackguy]

we apparently have to study all of chen's stuff

next question:

f(x, y) = xy
2x^2 − y^2

how do we prove that it is not continuous (or maybe is ) at (0,0)

 

[bigredboof]

did the lecturers give any hints on the exams??

 

[bigredboof]

any thought on the exam today?

no1 replying...
how did u go?

some of the 1st yrs ino told me it was better than they expected

 

[CloudStrife]

hahah...the exam was .....soso....couldn't say it was full hard...but u did need to know your stuff for higher marks ...algebra had more theory related questions....
i found the hardest question to be the group theory one coz i didn't know anything about intersections of 2 subgroups
