Yes I do understand the topics. Recording and listening is too much of a hassle for me to do on a nighly basis so I think I'll pass on that method. I don't see how colour coding helps me memorise notes, but feel free to share some light on this. tommykins, that would be an ideal approach for me...

I write out very concise notes for each dot point, but the next day I have trouble remembering them, despite having written them out numerous times the night before. Maybe this is because I write out notes for my other subjects as well, I really don't know. So this brings to a very general...

In the first topic of the economics syllabus, it has a dot point on: EU, NAFTA, APEC, ASEAN, CERTA I was wondering how much and what kind of information on each we need to know at the moment. Currently I'm using the Leading Edge textbook and I'm having trouble picking out the most relevant...

got it, thank u

1. Find the coordinates of the point on the curve y = x^2 at which the tangent is parallel to the line 2x - y + 1 = 0. 2. Find the coordinates of the point on the curve y = x^3 - x at which the gradient of the tangents is 11. 3. Find the coordinates of the point on the curve y = 2x^2 - 4x +...

1. The sum of the first 5 terms of an AP is 35 and the sum of the next 5 terms is 160. Find the first term and the common difference. 2. Prove that Tn = Sn - S(n-1) for any series. 3. The 20th term of an AP is 131 and the sum of the 6th to 10th term inclusive is 235. Find the sum of the...

that's correct, thank you.

Find the sum of the powers of 2 from 1 to 1024 inclusive. Can somebody explain how to do this?

thank you, I'll go through your solutions when I get more time. :)

huh? I'm talking about the Leading edge one..

I was looking through their site but they did not have answers to the economics textbook. I was wondering if they were ever released or if somebody here has a copy of it?

1. S is the point (4,0) and d is the line x = 1. The point P(x,y) moves so that the distance of P to d is half the distane of P to S. Show the equation of the locus of P is 3x^2 - y^2 = 12. (This curve is a hyperbola). 2. A is a point where the circle with equation x^2 + y^2 = 16 cuts the...

What do you have to show to prove that two circles touch internally?

Excellent, thank you!

Does anyone know the definition?

Thank you so much!

edit: i figured some of them

1. (a) Find the equation if the tanget at the point P(8,2) on the parabola x^2 = 32y. (b) If this tangent meets the tangent at the vertex of the parabola at Q, find the coordinates of Q. I need help with (b). 2. The parabola y = 4x^2 is reflected in the line y = -3; obtain the equation...

What happens if I come 2nd in a 2u maths assessment, and the person coming 1st does 4 unit maths and will eventually drop 2 unit? Does my rank become 1st when she drops or does it just stay the same? Thanks
