This is part of the QCE Specialist Maths course under Unit 3: Mathematical induction, and further vectors, matrices and complex numbers. In this post we look at Topic 2: Vectors and matrices and how to prove geometric results (review from the topic Geometric proofs using vectors) in the plane and construct simple proofs in three dimensions. Let’s check out this video to learn more about when vectors are parallel, orthogonal or neither!
