dude dont post answer it is not allowed :OQuestion 7 was horrible! not ever came in past papers since 2001... Only Add math students were able to understand the half question but time was short. Q11 was very easy as integration of curve + integration of line BC. Where C was (2,0) .. Further paper all after the break...... Wish all of you good luck!
Q3)
i) Perimeter of sector = ½(Perimeter of rectangle)
2r + rx = 4a
Sinx = a/r
a = rSinx
2r + rx = 4(rSinx)
2 + x = 4Sinx
Sinx = ¼(2 + x)
ii) x1 = 0.8
x2 = 0.7754
x3 = 0.7668
x4 = 0.7638
x5 = 0.7628
x6 = 0.7625
x = 0.76 (2 dp)
Q4)
i)
ii) tan²x + (6√3)tanx - 5 = 0
Let y = tanx
y² + (6√3)y - 5 = 0
Now you have to use quadratic formula. I am sure you can do that!
hah..no..there we can see each other writing on that board.what you mean bro ?" its just for painting
I need help in this too. It's driving me mad. What I would do I would draw it out on a graph paper, and count the boxes. *dead*http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w11_qp_32.pdf

Q10 ii) I've made the Argand diagram and did the shading. How to do the last part.. "Find the greatest value of arg z for points in this region."
Thanks
Can someone help me in question 6 of this paper: http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w12_qp_62.pdf
I don't understand these type of questions. How do we tell if two events are independent from each other?
mod = root of ( x^2 + y^2) =1Dug... if u rnt busy..please!
