whats school??????

lol how do u do q12 of senders hwk for polynomials.

Standard and Advanced scales the same. Standard and Advanced ALIGNS differently and because of the aligning, it is a lot harder to get band 6 in standard than advanced. BoS does the aligning while UAC does the scaling. Why the fuck wouldnt their scaling be the same when half our HSC...

Hi rgay.

hoohoho i see what u did there.

lol fobs doing general maths

Long divide.

inverse sin(x/2)

wait for 1 more day.

why dont u stop bitching. Q________________________________Q. no1 gives a shit about your timetable or op's.

if trollmeter says >10 then u should get 99 atar if <10 then tafe.

ah i see lol. Was thinking all real x but then roots are bigger than 0 :\. ty.

lol i meant x^2 -1 inside the brackets so... inv tan (x^2-1)^1/2

What about inv tan (2x-1)^1/2

Whats the domain of inverse sinx . inverse cos x/2

tell him to ask his math teacher.

i+3-4i-2 =1-3i

iii) If the roots are distinct then it passes through x axis 3 times. Therefore f(u) must be a negative value and f(v) must be a positive value. A positive value times a negative value is alwyas lesser than 0. therefore f(u).f(v)<0 f'(x) = 3x^2 +b = 0 therefore x= +(-b/3)^1/2 and...

3a+3b=3 a+b=1 a=1-b 2a^2 + ab + 2ab+ 2ab+ 4ab + 2b^2=-8 2a^2 + 2b^2 + 9ab = -8 2[(a+b)^2 -2ab] +9ab=-8 2(1-2ab)+9ab=-8 2+5ab=-8 5ab=-10 ab=-2 (1-b)b=-2 b-b^2=-2 b^2-b-2=0 (b-2)(b+1)=0 therefore b=2, a=-1
