omg i wrote ectothermic....then i went on to list some adaptations of an ectotherm LOL :((

Crap I just realised how screwed I am for this. I have not even looked at my pracs (any of them) and need to memorise that diphtheria smallpox polio junk. And I'm already tired. Well goodluck to everyone though :(

Could someone tell me how the whole band 6 thing works ? Like, how, a mark not in 90s may be equivalent to a band 6 or something ?

Omg, hated it. The clock chiming question got to me. As well as that infinite sum question and ofc, the last part -.-

Hey :) i was doing this question, saw the solutions, and don't know WHY they worked it out in that manner. Can someone please explain why the interest is to the power of both 12 and 18 in the second year ? (might be long, but please bear with me ?): Jacqui borrowed $400 000 from bank on 1st...

thankyou ! i appreciate it :)

Thanks, i had not been exposed to the unit circle, but it makes sense now. Thankyou :)

thanks, but why is sin(pi-x)=sin(x) ?

please help: lim sin(pi-x)/x x-->o The answer is 1, but i'm unsure of how to get that thanks :D

hi :) Could someone please help me out with this question, i'd appreciate it so much show that the curve y= (x^2-bc)/(2x-b-c), b>c, has stationary points at x=b and x=c

oh ok thankyou so much, so it's -f(x) not -f(-x) ?

So i'm doing harder curve sketching, and in the part where you determine whether the function is odd/even/neither, i have been taught two ways by two different teachers and unsure of which one to use Method1: F(x) F(-x) -F(x) Method2: F(x) F(-x) -F(-x) For method two, everytime i...

You're the best .

Thanks so so so much, makes alot of sense- i really appreciate it greatly !! All the best for your HSC- goodluck :)

salaaaaammmm :)))

I've been trying these questions for such a long time and dont even know the answers because there is no answer sheet attached ! :( QUESTION ONE: The gradient function for a certain curve is given by dy/dx= (x+1)(x-2)(x-3)^2 a) State the abscissae of the stationary points b) Investigate...

thanks so much (:

Can somebody please help me solve this ?:frown2: Find two numbers whose sum is 12 and which have a maximum product. Let the two numbers be x and 12-x thanks

Yeah, you're actually right about that, thanks (:

Oh my god. It never occurred to me to use simultaneous equations. Feeling so embarrasingly stupid at the moment haha :) Thankyou all so much!!
