    Kill off a topic.

    as much as i love mechanics, i don't think the topic "belongs" to high school maths. i think this should be moved to become part of physics while leaving more room in the maths syllabus for more topics.

    3 MC questions from a 2012 Trial HSC

    no because the 2 remains inside the square root while the 9 is taken outside the square root making it 3. so sqrt(2G(9M)/(4R) = sqrt [(9/4) x 2GM/R] = sqrt (9/4) x sqrt (2GM/R) = 3/2 sqrt (2GM/R)

    Difficulty of each topic?

    definitely hsc questions - both easy and hard - to train 1. accuracy 2. speed 3. problem solving. anyways, graphs can get tricky but in my opinion its the easiest. conics can get messy but generally straight forward. integration is fairly straight forward. mechanics - many struggle with this but...
