    Where can I find this Q?

    sin(3θ) = 2sinθ sin(2θ + θ) = 2sinθ sin2θcosθ + cos2θsinθ = 2sinθ (sinθcosθ + cosθsinθ)cosθ + sinθ(1-2sin^2θ) = 2sinθ sinθcos^2θ + sinθcos^2θ + sinθ - 2sin^3θ = 2sinθ sinθ(1-sin^2θ) + sinθ(1-sin^2θ) + sinθ - 2sin^3θ = 2sinθ sinθ - sin^3θ + sinθ - sin^3θ + sinθ - 2sin^3θ = 2sinθ 3sinθ - 4sin^3θ =...

    Another projectile motion Q.

    There's no need for sin or cos because the velocities are already given.

    My school had booklets if you didn't go. They didn't let us know till after the final date of payment tho, lol. Personally, I went. Slept through the Life Ready program lesson tho.

    Looking for some Grade 12 Force vector questions

    But don’t these questions take friction and other things into account? Doesn’t that make them out of syllabus or nah?

    Vectors q

    I just found 2 ways to express OQ & then equated it to find Lambda. My working is a bit different to Hughmaster. PQ = kPC OQ - OP = k(OC - OP) [Note: Head minus tail - both sides] = kOC - kOP + OP = kOC - OP(k-1) Therefore, OQ = kOC - 2/3OA(k-1) [Note: OP =...

    Vectors q

    Finished it. Just making sure is the answer lambda = 2/5? If it is I'll send you the working.

    Vectors Syllabus/Questions

    What Cambridge Lessons is this dot point referring to: ME-V1.2 Operations with Vectors - solve problems involving displacement, force and velocity involving vector concepts in two dimensions. If anyone has a question bank for the dot point, please send it through lol.

    Alright thank you. Do you recommend to having 1 or 2 “safety” courses in the earlier rounds or maybe even the later ones?
