More important I think is the working out. Using the common pythagorean triad of 5,12,13: the adjacent side came out as 5 units (adjacent side = square root ( 132 - 122 ). Opposite side = 12 Hypotenuse side = 13 Adjacent side = 5 Sin @ = opp/hyp = 12/13 Cos @ = adj/hyp =...

Tan @ = -12/5, Cos @ = -5/13, I hope that is right! :o

:shy: I bet YOU got the right way though. I would've said 1/11 = 0.0909090909090909090909090909...

I think I found it by chance on google (searched for HSC notes or something).

my maths teacher took past HSC papers for the first extension test... man I wish I did more past papers :hammer:

what's spot?

A sibling of mine had one for PDHPE and they got in the 80's as their HSC mark --> if that gives any reliable indication at all.

Wow! That was an amazing proof. Well done.

Possibly: (Advanced) English or higher (extension) Mathematics or higher (extension) Chemistry Physics Biology PDHPE Pretty much what everyone else said, but really, you don't NEED to do anything as they are ways around everything these days.

Cause it's colour-coded right?

Wow! That's commitment to colour-coding your work.

I was talking about Wespac. I think I must have just scraped a high distinction.

Year 12 will be what you make of it. A test of will-power, determination and consistency; the plight for academic excellence will in turn lead to the suffering and stress of many human beings (including time, relationships, health etc). In a world thriving on competition year 12 will be a...

When I received a High Distinction in Year 8 I got 88/120 (73.3%) if that's any indication of what you need (of course it changes from year to year). I reckon about 70-100% (percentage mark) would get you a high distinction, 55-70% a distinction, 40-55% a credit and 0-40% for a participation (of...

QFT. Chemistry is the science (bar senior science) closest to having snippets of Biology and Physics in it. Thus, it is possibly the subject that gives you a better overall picture in terms of scientific knowledge.

Salt and water?

When I drink hot drinks the steam makes the glasses fog up (haha).

You got straight A's. Well done mate. Keep it up.

That interesting means of motivation just made my day. Good on you.
