MAST20026

[Gloamglozer]

Dear Real Analysis With Applications,

I am writing this to kindly inform you that you and I will not be best friends this semester following our first meeting today.

Kind Regards,

Gloamglozer


I have a feeling this is not going to go down well at all and it was only the first lecture.

[dcc]

What a beautiful subject; I would have loved to take it.  You know a subject is really good when people groan about it being way too hard.

Who is your lecturer? (BARRY?)

[rustic_metal]

Groan can also mean it's taught badly or is really dry.

Cbf real analysis. I've done 2 years of uni subjects involving limits so far and really cannot be arsed doing another subject with yet more in it.

I hated acc maths 2 at first (acc maths 2 ~= MAST20026?) but around about 2weeks again I started to like it heaps more. Barry (forget his surname) was a good lecturer, but there's not much he can do for the more dull parts. And if you don't like the start, you'll love the applications stuff at the end

(acc maths 2 ~= MAST20026?)

MAST20026 is Real Analysis. It's basically a crapload of limits and proofs.

[ryley]

Sorry rustic_metal, I guess I wasn't too clear, accelerated maths 2 at melbourne covers enough real analysis to get you an exemption from doing MAST20026. So I wasn't just talking about my experiences with some random maths subject lol

[rustic_metal]

Oh right, sorry. I didn't see the ~ and thought you were saying "I think that's MAST20026, right?" My bad haha

But real analysis underpins <so much> of calculus, which is used for pretty much everything (including economics)

AM2 was good - except for the bits which came from Calculus 2 (differential equations, differential equations and differential equations).  Twas' Barry Hughes.

[Gloamglozer]

Yeah Barry Hughes is the lecturer.  He's good and it's not his fault.

What annoys me most is not being able to start proofs.  Once I get started and provided it's right, it's pretty straightforward from there.  It's trying to find where to start that's killing me at the moment.

EDIT:  It's either the above or not understand what the question is asking.  Like:

Let .  Recall that if , while if .  Prove that x = 0 if and only if

Lol calculus is perfectly doable without real analysis. And you only need very basic calculus for economics.

Yay, epsilon delta*

*Not actually enjoyable.

Barry is an awesome lecturer! i had him for acc 2, god he threatened death to so many people throughout that semester(oh and the black umbrella). Real analysis is hard at the start but once you get your head around the subject it will click, i recommend you have a look at the textbooks rudin analysis(truly a classic text for real analysis) or spivak's calculus. They really helped me wrap my head around proofs and the sections targeting sequence is really well addressed. Professor Ghitza teaches Real analysis in the second semester(i had him for complex analysis) has pretty good notes and you should go speak to him if your really struggling, he will probably have no problems in giving you his notes.

Let .  Recall that if , while if .  Prove that x = 0 if and only if

given , for all (obvious).

we know that for all .  Assume .

we note that , so (taking ), which is a contradiction.  therefore . QED.

The real question is - spot the implicit arguments (for example, if ).  I guess the essence of the question is the idea that if you can get arbitrarily close to a number, then you have the number.

I would hardly call multivariate calculus "very basic".

Haha, yes he's used the umbrella once in the lectures so far.  And I'll definitely go and have a squiz at the two books you mentioned.

And also, thank you dcc.    Greatly appreciated your help.
