I'm sure you're right, because I think the numbers are meant to be icky. So is theta the acute angle? (When my teacher did it, she just wrote the obtuse one, but I can't tell if her answers are messed up. Then again, she always took shortcuts and didn't explain them >.<) How about the...

I always get this wrong because I get confused between the + or - in: Rsin(x+θ) , Rsin(x-θ) , Rcos(x+θ) , Rcos(x-θ) Here's one example: a) Change y= 3cos(x) - 4sin(x) into the form y=Rcos(x-θ) and sketch. b) hence solve 3sinx - 4cosx = 2 Thanks :)

The gravity being... g = 9.8 ms^-2 towards centre of Earth? Or a different planet now? I'm not suggesting to be too relaxed - I'll still try to get decent marks - just not this whole "3 hours study per night" thing.

I really don't get what all the fuss is about. I actually find it infuriating when people are like: "It's the HSC! Worry everybody! This is the most important thing EVER. It's so important and we have to have no lives because all we're going to do is study! Have you started studying yet? Why...

Well... now I just feel like hanging myself... can't even think about solving any one of those...

... My teacher wrote stuff in my journal... HER FAULT!

I suppose it just depends what you can make out of it. If you think you can make it work, go ahead and try :) I personally find it harder to do lots of action, because then my descriptions go haywire. Just make sure you get in your ideas and some character development. If the "dramatic and...

Required to prove. (or remains... whatever takes your fancy)

Err... welcome! I assume you're trying to make a calorimeter...? In which case you may have thought of using a copper beaker, some sort of lid (cardboard) and sticking the thermometer through that, and tinfoil insulation round the outside... then taking into account the specific heat capacity...

That's what the 06'ers at my school had. It was soooooo painful... they played it not once, but TWICE. We all had to sit there in assembly bashing our heads against the chairs and drowning the noise in 'Smells Like Nirvana' by Weird Al.... That's what I did anyway... Legend.

So this has 7 function values (or 7 ordinates). It has 6 subintervals, 6 strips, and 6 trapezia.

So THAT'S how it's done.

Chem prac exam - all was going well, I checked my calculations... Walked out of the exam then thought "0.09875 rounded up DOES NOT equal 0.01". No one over 8 years old should get that wrong. Somehow, I managed. Bloody lunatic.

Yeah, I think so. But that's a mad score. 0/100 I'd love to see that. :P

I get mixed responses to mine now :) Some people are like "hey that's cool" and others... "are you from the KGB or something???" LOL

Reminds me of: "The quicker you do it, the quicker it better be done." Not a teacher quote though, that was my dad. lol

Maths exam today was lame. Differentiate this, integrate that, waste your time proving that this rotten blob on your page is a parallelogram... Rubbish.

Ok, thanks guys. My mistake, (2) was supposed to be ∫ b^x Now lets just hope I can remember things... :S

Could someone please give me the theory for this? Just in case it's in the test tomorrow!!! eeek... It's like: but I think (2) might be wrong... Help please. :)

Lol, I'm not impatient. My hand just slips... or I forget which way is 'off'. Anyway, thanks guys. I'll see how I go next time. :)
