Nop, I haven't gotten up to that yet and nop this doesn't mean I can't answer it by the end of the hsc

Lol. I have so many textbooks, etextbooks. muahahaha

You're a genius. Still here to annoy people, yep. Not realising how much life you're losing,yep. Not realising that noone gives a crap about you here no more, yep. Not realising you have excess fat molecules, yep true genius

Re: what should u do ifu get bad maks in ur first maths test Just give up maths like I did ^that's what I would've said if I received a bad mark in maths. lol Just read cambridge 2unit/3unit. Read all of it except the study notes section.

Cool Now the question isn't that interesting anymore lol (to hsc students)

what he said you can prove it easily by letting p/q being a root where p and q have no common factors.

The answer to those questions specifically is "There aren't any" Judging from your reply, you didn't post the right domain

^ lol Imagine a paper with just those types of questions...you'll have blank writing booklets XD

ok yea, that was a bad example since I made it on the spot. Though I'm talking about when the question says there's at least 1 rational root...but you knew what I meant I hate using the calculator but oh well

There's a better way than substituting all the p/q values to find a rational root right? I use my calc for it, but it still takes forever! So is this all about luck? e.g. 2x^3 -1=0 potential roots are +\-1/2, +\-1 but a much longer one

Have a feeling he wants to know what rank he should come for each subject

what s the point in knowing this figure?

Yea people with 10 units do. IPT is a great backup IMO. If you have a knack for computers then you can easily get high marks with very little study/revision.

Trolling and then not trolling? If you've emptied it a long time since, chances are they're out of the hard drive

wow you guys have finished learning everything? LUCKY I'm not even half way :(

for 9 find relationship between h and r find tan(x/2) and then do it. I used the double angle formula and then realised I could've done I via calc. Then use dV/dt=dV/dh x dh/dt I can't picture 24 in my head. ???

18 can be just a harder 2unit question distance = speed x time Let time be t and distance be c Use the cosine rule and then find the rate of which c is changing

Great post, great waste of time however...

ffs product rule . Both answers are wrong

Magnetic induction is vague. I thought he didn't express it correctly
