I try to do at least 3 hours a day (including homework and study periods at school)

Thanks :) Probably just commerce, you?

:) :) :) :) :) :) :) :) :) :)

no t-formula is needed I think. I treated it as a normal variable and I still got the right answer I could be wrong though

OMG I'm so sorry carrot and everyone else that "t" in the first part (i) was meant to be a 1... apologies for the confusion

I'm not exactly sure, I copied the questions word for word so I don't know any more than you unfortunately. I treated it as a constant in (ii) though. I will type out my solution in a sec EDIT: nvm, misread the question Thanks for your effort :) This question might look familiar in a certain...

\\$(i)if $y=\frac{1}{1+\tan{x}}$ express $\frac{dy}{dx}$ in terms of $\sin{2x}\\$(ii)By substituting $x=\frac{\pi}{4}-t$ show that $\int \frac{dx}{1+\sin{x}}=\frac{1}{2}\tan\left ( x-\frac{\pi}{4} \right )+C\\$(iii)Using the results of (i) and (ii) prove the identity...

congratulations! (again :)) Does that mean that you can accept the Scientia at the same time? ;) ;)

u mirin' my inverse trig skills? :p

yep, I totally made that retarded question up by myself. It was all my idea aye?

By a few marks I think, if I didn't stuff up my second assessment I reckon I could break into the top 5 easily, oh well Yep, although most of the lessons were just handing out the syllabuses, talking about the outcomes/rubric before finally moving on to the content lol

I do not know of this "Lord Iron-Balls" you speak of Does it look like I'm associated in any way with this guy? :(

no idea who you are talking about m8 thanks pretty happy considering the competition. The gaps must extremely close since I lost one mark each for the 2&3U yearlies :(

so apparently I'm in the top 10 at school for 2 and 3 unit maths (based on this weighted index used for ranking people who want to do 4U) Hopefully I can keep this up in year 12...

Re: Physics Tutoring For HSC 2013 -- Starting Term 4, 2012 [FILLING FAST!] ahahahaha now who wouldn't want a tutor with a sense of humour like that :p

nah it's not your fault most people just got carried away with discussing what they were going to do at the meat lol
