The rectangle box shown in the diagram has dimensions 6 cm × 4 cm × 3 cm.įind, correct to the nearest one-tenth of a degree, the size of the angle AHˆ C. (a)įind a if the point (a, a – 1, a – 2) lies on the plane.Īnswers: (a). ! ! ! ! The vector n = 2 i – j +3 k is normal to a plane which passes through the point (2, 1, 2). Find the shortest distance between the point P and the plane π. (3)įind an equation of the plane π which contains the line l and passes through the point S. (b)įind an equation of the line l which passes through the point Q and is parallel to the vector PR. (7)įor the remainder of the question, use the value of c found in part (a) for the coordinate of the point R. (a)įind the value of c so that the vectors QR and PR are orthogonal. If OP and OQ are position vectors for the points P and Q, use your answer to part (a), or otherwise, to find the area of the triangle OPQ.Īnswers: (a) …………………………………………. 4x – y + 2z = 1 2x + 3yįind a vector perpendicular to the two vectors: (Total 4 marks)įind the value of a for which the following system of equations does not have a unique solution. So, I guess my question is: can anyone tell me a way to study Economics in the UK without having Math HL? Is there any way I can bypass that requirement? (long shot, but maybe I can test out of it, i.e.Find the coordinates of the point where the line given by the parametric equations x = 2λ + 4, y = –λ – 2, z = 3λ + 2, intersects the plane with equation 2x + 3y – z = 2. I'm aware that I'm way past the deadline for Oxbridge applications, so I was really only eyeing LSE and UCL as they both have fantastic Economics programs, especially LSE. However, I want to study Economics, and I've heard that in order to do so in top UK universities one needs Math HL, while I'm currently taking Math SL. This obviously opens a lot of doors in the UK as they use predicted scores as one of the main requirements for admissions. Meanwhile, I just got back my IB predicted scores - a 44/45. However, my GPA (3.78) is not quite as high as it could be for the very top institutions, even if I'm still going to apply there. Originally, I was only applying to US colleges as I was pretty set on attending there. I know it's a bit late to be asking things concerning applications to the UK as most of them are due in a month but here I go.
