    :) 3D loci's are the 3D versions of what we use. An equidistant 3D loci from one point is a sphere, Mostly, Spheres and Cylinderical loci are what we need to learn. I haven't looked at this chapter for some time now. I have to revise it so I'll tell you all of them by morning.

    Well, this type of notation is used in add.maths so it's easy to understand, (a) k = 1+5/3 = 2 (b) 3x - 5 = cx + d, So, by comparing, c=3 , d=-5.

    More than half of what the line measures. Just take a big measurement that is seemingly a little larger than half of the line.

    Questions like these don't come very often in paper one. If it does come then yes, take, 2 * 3 * (root 7^3) which means 6 (root 7^3). Either express it this way or use estimation to calculate a rough value.

    Yes. What you mean by length?

    Loci; Equidistant from ONE line = Parallel line to that line. Equidistant from ONE point = Circle. Equidistant from TWO points = Perpendicular Bisector. Equidistant from TWO lines (with common vertice) = Angle Bisector. These are the four most common and widely asked loci.

    The prime factors must have been 3^2 * 4^2 * 7^2. So, from this, you can easily evaluate the root, root 7056 = 3 * 4 * 7 = 84.

    What was the first part?

    You always express both the quantities in the same unit for 1:n ratio, so, 10 m = 1000 cm Therefore, 1 cm : 10 m = 1 : 1000.

    Everything comes. The 25 questions (mostly) are almost always from different topics so there is little chance that anything is left out (except pure trigonometry and coordinate geometry of course). So, be ready for everything. THE BEST WAY to learn the congruency and similarities at this time is...

    If the two balls are of different colors then the probability of choosing one of the colors is 1/2; if you're asked to choose again from the same bag (with the two balls), the choice is again 1/2. It's not of 2 balls waise, it's usually of dices with 6 (or four) faces.

    It was a little tougher but not that hard. In fact, all the latest papers (of this century :P) are easy. Unlike the 90's. I did the 2005 paper just earlier, found it pretty easy except a certain AE vector part that I got wrong.

    Yes. Always look for the from. You know how bad-*** these CIE peepalz can be sometimes. ;) Yeah, revise circle theorems, probability, rates & ratios, loci and transformations. These are, what I believe, to be the most important P1 topics.

    There's only one red so, Probability = 3/4 * 1/3 = 3/12 = 1/4

    FROM B means that north is ON B. And it's almost always bearing OF A from B or similar.

    Equilateral triangle means that each angle = 60 deg. Bearing of C from A = 75+60 =135 deg.

    I didn't. It's the ONLY method for problems like these. :P Yaar wohi 5 class main nhi krty thy? Lambi lambi kahaaniyaan? :p...

    This came in one of my class tests. :D Use long division, when they asked for the working, just use the good ol' long division method up to 3 decimal places and round off appropriately.
