    Study Advice From Now Until The HSC

    *shakes head* By using your rule which alternates between the addition of 2 and 4, since 2 + 2 = 4, then .: to get the number before it, it would need to be 1 + 4 which = 5 or 2 - 4, which = -2 and not 2. :p .: I agree with baby beanie :)

    Differenciation Help =)

    [/B] I think the teacher missed a rule...I don't get WHY you do that. I just took it by looking at the answer that the "derivate of the power" goes out infront of the rest ie that's where I thought the 3 came from. Yes thanks FishSauce you did get the right answer. :):)

    Differenciation Help =)

    Thanks, now I know we haven't done that rule. :) However looking at the answers shouldn't it also have the derivative of the power x as well? eg dy/dx=f'(x).ln(a).a^x ???

    Complex Number help :)

    Everyone on BoS is so helpful :D Anyway cuz I can't seem to edit my post, I can do 6 a) and b) but I got really stuck on this one. Where z=cisq, prove the following: d) -(1+i) (( √3) + i) z = 2(√2) [cis (q - (7π/12))] (the spaces mean multiply)<O:p</O:p

    Complex Number help :)

    Thanks :) but I did a) and b) but I didn't understand c) Well the answer for 4c is Cos (7π)/12 = [1+(sq-root3)]/(sq-root8) Sine (7π)/12 = [1+(sq-root3)]/(sq-root8) I feel like I'm missing something really obvious, coz they're conjugate pairs or something :confused:

    Complex Number help :)

    If z = [1+(sq-root3)i] x (1+i) 4a) Express z in the form x+iy, where x and y are real :)

    Recommended Texbooks/Study Guides for Preliminary HSC?

    Re: Recommended Texbooks/Study Guides? Text books aren't that important esp for prelim. You could borrow text books from your friends and family for a night or two to write notes and stuff - I'm sure they'll be more than willing to lend them to you. Raid your town library or school...

    Hey BoSer's I'm having some trouble with complex numbers, any help would be greatly appreciated 4. b) by expressing 1+ (sq-root3)i in mod-arg form, show that z = (sq-root8) cis (7π)/12 that's the first part of the question which I can do, here's where I'm lost c) Hence, find the exact...
