    exact value

    LOLOL the question wasnt find exact values, dw i got it was a show question xP exploitable where do you get these epic animations, lags typing as well :o

    ATAR Estimate - I need 94.55

    lol this guy is just going with the flow you would need his interal mark to approximate his ATAR. Without knowing this, you don't know how well he is going even with those ranks

    exact value

    i still cant do it with the double angle result, i use the expansion of tan angles over 3 and i dont get the answer still.. lol dw making it over 3 is wrong method how would you do it? solution please

    trig

    Prove algebraically that if n is a solution of the equation 2cosx = 1 - .5x, then -2 <_n<_6. when showing this graphically is the negative solution(3 solutions) on the left of y axis or right of y axis. The answer at the back of book says on the left, but that is above the x axis meaning y>0...

    polynomials

    iuno xD thought it was monotonic but guess its not, poly is too tedious to type up

    Asymptote

    yeah that cos why put a fraction in another fraction, no point

    Harder Parabola Question

    only point with 3 normals is (0,0) im guessing

    polynomials

    if x is a factor of P(x) , P' (x) is also a factor P(x) = x^3 + ax^2 + bx + 12 P(1) = 0 = a+b+ 13 P'(1) = 3+2a+b => b = -(a+13) substitute, a = 10, b = -23 P(x) = x^3 + 10x^2 -23x+12 --->could also be done with product of roots etc. When P(x) is divided by (x+1) and (x+3)...

    what on earth o-o this looks like a physics question

    Asymptote

    quoting from hscishard "Divide x (highest power) on both num and denom" on your maths equation 1 / (x-1) is alrdy in fractional form, so if you limit that to infinite it would approach zero. What is the need of dividing by x again. Isn't that just complicating things :nod

    Proving the Volume of a Sphere using the Shell Method.

    i think drongoski said it all. rotating semi circle, circle = same shape, could make x the subject and do dy as well

    Discuss: Study techniques!

    lol i do study until what i was expected to stop at (set by myself) and then take break, then repeat. I personally always finish mx1 first before touching 4u. But other than that, its pure 4u after that. Hmmmm approx time for each: mx1 - 7 ( depends on workload) -------------> both really...

    Harder Parabola Question

    origin for the point? with just normal parabola with vertex at (0,0)

    integration question

    yeah only 4u requires it, but do you get marks deducted if you miss out the absolute value? btw was bos down for like 4 days? or did mine just stuff up

    Annuties Strategies

    you are overcomplicating things. my suggestion would be practice, over time i'm sure you'd know which one to use and which to not
