Not sure if you're mocking me or... But thanks for your help. XD

OHH... took me a while to understand what you said... So... basically after I state 'the minimum value of blah blah will be 2' I would also say for what values of 'x' will yield the minimum value? i.e. The minimum value of ' y = (x^2) + 1/(x^2) ' will be 2 and this value will be obtained when...

c) Use the result above to find the minimum value of ' y = (x^2) + 1 / (x^2) '. so from a) i could just write... from (a) : (x^2) + 1 / (x^2) is GREATER THAN or EQUAL to 2 and from that could I say the 'minimum value of blah blah' will be 2? or is there something more i need to say?

I kinda said that too... didn't I? LMAO but thanks for verifying.

Noo... i did that and i deduced the answer. It's just the part when it asks "When does equality hold?" that I'm confused about.

a) By expanding ' ( x - y ) ^ 2 ' prove that ' (x ^ 2 ) + ( y ^ 2 ) ' is GREATER THAN or EQUAL to ' 2 x y ' for all real numbers x, y. b) Deduce that ' (a + b ) / 2 ' is GREATER THAN or EQUAL to ' sqrt (ab) ' for all non-negative real numbers a, b. When does equality hold? Is the answer...

LMAO I didn't. I guess that's a point against for online interactions. And I was just wondering, that's all. Just wanted to clear that up, and thanks!

Yea I know. I just wanted to check? And how do you know I have homework? It says you graduated in 2010?

I was wondering if there was any homework we needed to complete for our tutorials this week? I'm doing: ACCT 1501 and ECON 1101. Yes I know I could check on Blackboard, but I'm having a hard time navigating through it, so I just wanted a quick answer.

Commerce / Science (Advanced Mathematics) IDK what majors to even go for, but maybe QR? Although I've heard its not as great as it sounds. =/

So I've recently accepted an offer at UNSW for 'Bachelor of Commerce / Science (Advanced Mathematics)'. The thing is, the enrolling process is a BIT confusing. So for Commerce, I have: - ACCT 1501 - ECON 1101 - INFS 1602 - MGMT 1001 And for Science (Advanced Mathematics), I have...

BUMP!

Could someone differentiate for me, adaptive optics, interferometry and active optics?

Thomson manipulated the strengths of both the electric and magnetic field until the beam passed through both fields undetected – they travelled in a straight line (this is known as the velocity selector) F_B=F_E→qvB=qE→v=E/B as the electric and magnetic fields can be calculated, then the...

I still don't really understand 2. Doesn't it cut the MAXIMUM amount of flux lines when the coil is PERPENDICULAR (i.e. at Q)? But for the rest I get them now. Thanks!

Nope. =(

Well, if Maths is your weakest subject, then I'd suggest you just don't try in it. Treat the period in class as a free period and focus on your other subjects in class or something. Just because it's compulsory at your school doesn't mean it will be compulsory to your ATAR. And in regards to...
