i a^4+b^4+c^4 to be -2p^2 i did x^3=1-px so x^4=x-px^2 thn subbed in a,b,c and then went from there

better than me, 18 on my 4 unit maths exam =[

tanx= tan(x/2+x/2) =(2tanx/2)/(1-tan2x/2) =2t/1-t2 then just draw up a right angle triangle and find an expression for the hypotenuse

Re: What to do during days after exams? well next monday im hoping to burn everything english related and after my chemistry exam, im heading straight to the pub =]

how good is de moivres theorem when it comes to these questions

my teacher said you can still use stimulus material but you just dont say that's where it's from.

you arent allowed to use the physics formulas in maths you have to derive all the equations

if you still need help with it: angleMJK = 15* so using the sine rule: sin15/mk = sinJMK/JK sin15/18=sinJMK/20 sinJMK= 20sin15/18 so JMK = 16*43' therefore KML = 75* - 16*43' =58* (nearest degree)

integration by parts is just the reverse product rule. but yeah i think anyone who can come up with these formula's is pretty insane

haha except that for q8 the top mark wouldve been about 3 if that

id be agreeing lol

haha i just did that paper i got about 105/ 120 =]]] umm what questions do you need answers to??

yeats is a fuckhead

haha heaps dragged down namu didnt you get like 119/120??

theres some savant dude that recited pi to 20,000 digits on some thing called pi day took him like 8 hours he learnt it in 2 weeks aswell

AAA and equiangular are the same thing idiot

yeah when i was doing 2 unit tests in year twelve id do the test twice, then have the time to redo the ones i still had small uncertainties about.

definitely mechanics, volumes, and integration they are the best

why do ppl do this to themselves? then post it on the internet
