Well if we're going to start mentioning things that only about 6 people do, did you know that UNSW gives you the chance to be able to have your face on a massive 30x20m or so banner that they will design and print out, and hang it over the side of the Mechanical Engineering building in full view...
You do off the paper work to show it.
And then in your proof, you'll show that choosing that particular value will make it work out. So you'll go through the working you did off-paper, but in reverse.
see with your proof, you're starting at the end and then go back again
The proof's structure, should be:
Let ϵ > 0. Choose δ = ϵ/3. Suppose x is in D, and that 0 < |x - c| < δ. Then: |f(x) - L| < ϵ.
Follows the definition exactly.
Not "Let ϵ > 0." and then "|f(x) - L| < ϵ." and then go...
"Let f be a function defined on an open interval D containing c. Let L be a real number. We can assert that
lim (x->c) f(x) = L
if for every ϵ > 0, there exists δ > 0 such that for all x in D and
0 < |x - c| < δ
we have,
|f(x) - L| < ϵ "
Your proof should follow the definition.
So, see...
http://www.timetable.unsw.edu.au/ will tell you who the course authority is, and then you just google their name with "unsw" at the end and that should direct you to a staff directory where you'll find their office/email/etc.
You can do marketing in a Media degree? I think you can only study that in Commerce.
Anyway, I might be wrong about that.
To you, if you want to differentiate yourself and get a job in the graphic design industry, you should set yourself apart during uni. Supposing that is where you want to...
But would they know this?
I doubt a Year 10 student who wants to pick law won't pick Legal Studies because they know as a fact that it's different to what law is at uni, in general.
