Could be the 6-8 marker in Q1 paper one. Doubt if they'll ever ask us to write an interview or journal entry for a 20mark extended response.. u reckon? i was at the seminar too, but didnt attend the last session, modB. Peer pressure. sighs~

lol.. isn't it too late to learn new stuff this stage (for 06's)? just stick to the way ur most comfortable with and don't make any mistakes.

The general formula (θ-α)= πn + (-1)ⁿsin^-1(1/√2) where n is an integer n=0 (θ-α)= π/4 n=1 (θ-α)=3π/4... ususally the question will indicate a range eg 0≤x≤2pi, or it will ask u to find teh general solution.

How about . . . and . . . . . . . ... . . i suppose they can still form triangles..

what difference would it make if 3 pts were collinear?

next Q: a coin is biased so that in any one throw there is a constant probability P (where P =/= 0.5) that the coin shows heads. In 6 throws of the coin the probability of 3 heads is twice the probability of 2 heads. Find the value of P

0.5 --> 0 0 --> 1 ⁰∫₁(1-x)(x)⁴ (-1/2) dx = (1/2) ¹∫₀(1-x)(x)⁴dx answer is +1/60

Q2 a) e^x=4x+8 let f(x)=e^x-4x-8 f'(x)=e^x-4 3-[(e³-12-8)/(e³-4)] =2.9947 (4dp) b) i) asin(x-α)=asinxcosα-acosxsinα acosα=1 asinα=√3 a=2 α=pi/3 sinx-√3cosx=2sin(x-pi/3) ii) 2sin(x-pi/3)=2/√2 sin(x-pi/3)=1/√2...

the time of flight is 1.857 seconds, so divide distance 13 by 1.857 = 7.0005 m/s i've edited my ans in the other thread.

what's wrong with ur answer? i would've done the same...:confused: The 1st face has 8 colours to pick from, 2nd 7 choices.... and 6th 3 choices. = 8x7x6x5x4x3

next question: suppose the roots of the equation x³+px²+qx+r=0 are real, show that the roots are in geometric progression if q³=p³r. Hint: let the roots be a/b, a and ab

hi, im just wondering how does the extra 1 unit that i have is counted in my best 10 units. im sure that that single unit will count towards my uai since im doing quite okay in that subject (ext1 maths) so does the uac or bos ?? splits my worst 2-unit subject? say my mark for physics is 66/100...

next question: y=f(x) is a linear function with slope 0.5 i) find an expression of the inverse function of y=f(x) ii) hence find the slope of y=f^-1(x)

Next Question let f(x)=e^x + e^(2x) find: f inverse (x) state the domain and range.
