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 reviewing the concepts of vectors from Unit 1. Here we will perform addition and subtraction of vectors and multiplication of a vector by a scalar algebraically and geometrically, and interpret these operations in geometric terms.
Adding and subtracting vectors
Adding and subtracting vectors gives us the resultant vector. This can be thought of like what happens to an object when two forces are acting upon it, or the final direction of two objects after they collide.
