Thanks heaps. I've been working hard on my maths, and in the trials i got 47%, and now ive lifted it to about 75% in the last week. Still have another 2 to get to about 85-90%. We'll see what happens. Your input is appreciated alot mate. Cheers

I've slacked of during the year, and now have my head in the books. So wondering if anyway could give me an idea of the highest UAI i could get...or what a relistic UAI could be for me. Mathematics - Lower end of about 50 English - 30/50 Biology - 9/20 Chemistry - 15/23 Physics - 10/23 And i...

I think it is in the average school's list. Chatswood High School. We had a 99.3 last year. but yeh...

Haha, thanks bud. Appreciated. Ive got and oldy book, 1976-1998 of past HSC exams, it has answers. But i need the more recent ones, as ive been doing the 2000+ papers. Yeh i guessed that much, damn school. Anyway, cheers mate.

Anyone know of any links to answers from old HSC exams... Thanks.

Thanks heaps. I see my stupidity there. Cheers And yeh i got that derivative....just wasnt 100% sure.

Consider the parabola y = x2 − 8x + 4. Find: (i) the coordinates of the vertex, (ii) the coordinates of the focus. for (i) i think i found it to be (4,0) through completing the sqaure (ii) but i cant exactly work out where the focus is. My guess it is still at the same place, but that doesnt...

Due to our class having a student teacher for this topic, i didn't actually learn it (learning it now) Problem with this question - A coastal defence cannon fires a shell horizontally from the top of a 50.0 m high cliff, directed out to sea, with a velocity of 60.0 m s^-1. Calculate the range...

Could someone link me to some online poems of Gwen Harwood (in particular Glass Gar and Prize-Giving) To be exact and easily understood, im looking for a Print out of the poem. Thank you in advance to anyone who can help me P.S. If anyone also has them in a word document or something, i would...

Thanks alot! That is what i was looking for, i couldn't work out how it was powering things!

That is excellent information, backing up the others, but i am still not understanding the one thing...how does it actually power things up, if the electron is going back and forth...

Ok, i understand, but since it goes back and forth, how does it power things (so does an electron go through something, then in 1 hertz, turns around and comes back through the obejct?) (object = whatever it is powering)

I have to post here to get some attention of people, since i kinda need to know this exactly by tomorrow. But if you could look at the link, and give me a hand, that would be appreciated! http://community.boredofstudies.org/264/motors-generators/116094/need-help-understanding-ac-currents.html

Thanks Not-That-Bright, but thats not exactly what im looking for, the info you gave me is also nice. What i am actually trying to find out is, why alternating current..is alternating current. Why not use DC current (why cant it be used in Transformers) for everything instead. Sorry to be a...
