    The killer was a psychopathic maniac who went after the helpless victim and literally beat him and shoved him to death. It shows that he was either clearly not in his senses (drunk) or perhaps was very angry at the victim for some reason. I really don't have an idea about serial killers. :p

    They all take right turns, which means that they all will be on the 'going' lane of the road.

    I've edited it. Sorry for the mistake. Edit: Gradient CD was incorrectly calculated (it should have been -ve).

    y = (cos x)^-1 dy/dx = sinx (cos x)^-2 dy/dx = sinx (1/cos^2 x) dy/dx = sinx (1/(1-sin^2 x)) dy/dx = sinx/(1-sin^2 x) This can also be written as, dy/dx = 1/[(1-sin^2 x)/sin x] dy/dx = 1/[(1/sin x) - (sin^2 x/sin x)] dy/dx = 1/[(cosec x) - sin x] dy/dx = 1/(cosec x - sin x)

    (i) Explanation: AC is the diagonal of the rectangle, the midpoint of which lies on the line y = k (where k is a constant). Now, Midpoint of AC = (6,6), therefore the midpoint of AC, B and D lie on the line y = 6. Hence, y-coordinate D = 6. Solution: (ii) Gradient AD = 0-h/-2-6 = -h/-8 = h/8...

    The types of questions that came in the 1990s don't come in papers now but they were harder than the current papers so if you want to solve them for practice then go ahead, it'll only make your Maths better.

    Computer Studies 7010: 2014

    Buy the IGCSE Computer Studies book and go through it thoroughly twice. Learn all the definitions/terms by heart. Develop clear concepts about every topic mentioned in the syllabus. Practice past papers, paying special attention to algorithms and system flowcharts. All in all, just go through...

    Solution: y = 1/(2x+1) Integral = [ln(2x+1)]/2 + c Using range 1 to 13, Integral = { [ln(27)/2] - [ln(3)/2] } (We ignore the constant c in definite integrals). Integral = (ln 27 - ln 3)/2 Integral = (ln 9)/2

    Yeah, sorry, I solved it in a hurry and hence the mistake. For other two vertices, you need to simultaneously solve the NON parallel line equations. So, you need to simultaneously solve: (i) y = 2x -3 and x - 2y = -9 (ii) 2x - y = -9 and 2y = x

    They have given you the vertex, which means that you know that (2,1) lies on both the lines for which you have to the find the equation. Since it is a parallelogram, opposite sides will be PARALLEL, which means equal gradients for opposite side lines. Solution: 2x - y = -9 Gradient = 2 (2,1)...
