Want to see more papers!

Wait so you had to prove the sum to products formula for 5 marks? Practise those papers (maybe one's from here seeing as the 3U papers should have MC)

Is this the isosceles triangle one? I liked that question. Seemed so different from other questions :D

Excellent marks & ranks :) Mind if i ask what is your school rank?

Cheers! You too man, gunned everything and came 1st in almost all your subjects srsly admiring that English mark of yours actually, all your marks haha

Re: Official BOS Trial Examinations: Spring Edition. You make the papers sound frightening.. although something i'm looking forward to :) Count me in. Also if possible, earlier dates?

lol what do you mean? i think i was off early last night..

You could just look up your school's ranking. http://bettereducation.com.au/results/hsc.aspx If it's not there, look back to previous years where they listed more than the top 100.

Re: MX2 Integration Marathon I did not know you were allowed or could do that..

Re: MX2 Integration Marathon \mathbf{1.} \int \sqrt{\csc x - \sin x} dx = \int \sqrt{\frac{1 - \sin ^2x}{\sin x}}dx = \int \frac{\cos x}{\sqrt{\sin x}}dx = 2\sqrt{\sin x} + c \mathbf{2.} \int \frac{dx}{\sqrt{e^x - 1}}dx $Let $ u^2 = e^x - 1 2udu = e^xdx \frac{2u}{u^2 + 1}du = dx...

Depends on your final course mark relative to others after it's all been put together by your school.

Re: ITT we help examine to get 85 in his Maths extension 1 yearlies so he can do 4 un Draw a quick sketch. Probably something you're more comfortable with.

i cbb scanning. will PM u

Re: ITT we help examine to get 85 in his Maths extension 1 yearlies so he can do 4 un Equating coefficients means comparing the coefficients on both sides of an equality sign. E.g. If a_1x^2 + b_1x + c_1 = a_2x^2 + b_2x + c_1, it can be said that a_1 = a_2 \; ; \; b_1 = b_2 \; ; \; c_1 = c_2

who do you need?

Re: ITT we help examine to get 85 in his Maths extension 1 yearlies so he can do 4 un Try this question: $If $ 2^x = 5^y = 10^z, $ show that $ z = \frac{xy}{x + y}

what are you during those times?

how are you not a lemon?
