    People who have given SAT's..

    If you are planning to go the states, then SAT is important. Most of the universities don't even care about your A2 result, all they need is your O level result, AS result and the SAT scores. And if you've like a really good SAT 1 score, you can get fee waivers too.

    Mathematics 2012 P32 QP and Solution

    I did but didn't complete it. Like I said above, I stopped at the point where we had kept both the perpendicular distances equal and cancelled out the 3's in the denominator.

    Mathematics 2012 P32 QP and Solution

    smzimran: Did you try attempting the vector question part iii? I had done it till the part where we had kept both the perpendicular distances equal and then cancelled out the 3's in the denominator. Any idea if I'll be getting any marks for this?

    Mathematics 2012 P32 QP and Solution

    I mistakenly wrote the '-' sign instead of the '+' sign, I am trying to correct that in the pdf. Secondly, I guess that the '- [tan^-1 (3)]' you've written is wrong. Because, in no way we can put a '-' sign behind '[tan^-1 (3)]' just because it was '[tan^-1 (-3)]'. It would've been correct had...

    Mathematics 2012 P32 QP and Solution

    I guess you'll get some marks because if according to 'cos^2 x' your final answer will be correct, error carry forward will be applied over there then.

    Mathematics 2012 P32 QP and Solution

    I didn't know how to do it. Secondly, I wonder what the mistake is. Question 7iii in this paper is the same as Q7iii which came in June 2006.

    Actually I wrote the wrong question above though the solution is completely correct. The equation was 'y = 3 sin x + 4 cos^3 x' and if you differentiate it, you get 'dy/dx = 3 cos x - 12 cos^2 x sin x'.

    maths p32 answers

    Rightly said. y = 3 sin x + 4 cos^3 x dy/dx = 3 cos x - 12 cos^2 x sin x 0 = 3 cos x ( 1 - 4 cos x sin x) From here, we get the first stationary point. 3 cos x = 0 cos x = 0 x = pi/2 0 = 1 - 4 cos x sin x 0 = 1 - 2 (2 cos x sin x) 0 = 1 - 2 (sin 2x) 2 sin 2x = 1 sin 2x = 1/2 The range...

    Good thing but doesn't really matter. Both the solutions are correct. It's just like I am writing it as 'y = -1 + 2' while as you are writing it as 'y = 2 - 1'.

    No, that's wrong. Though I know what you're trying to say. You would've written it like this: ln e^(-y) = ln {(3/2) - [e^(2x)/2]} -y = ln {(3/2) - ln [e^(2x)/2]} -y = ln {(3/2) - (2x)/2} But this is the wrong method, we can not multiply 'ln' to the numbers inside the bracket. Take this for...

    Math 32....how was it? :/

    You actually differentiated 'e^2x' instead of integrating it. I have no idea about how many marks you'll get as even the method isn't correct.

    Math 32....how was it? :/

    y = x^(1/2) ln x Volume = pie ( y )^2 Volume = pie [ x^(1/2) ln x ]^2 Volume = pie [x (ln x)^2] Now use integration by parts to integrate 'x (ln x)^2' x (ln x)^2 (x^2/2)(ln x)^2 - [x^2 /2 * 2 ln x * 1/x] (x^2/2)(ln x)^2 - [x ln x] Now integrate 'x ln x' x ln x (x^2/2) ln x - [x^2/2 * 1 /x]...
