Vectors - Scalar Product and Angles HL
In this topic, we will look at finding the angle between vectors in different circumstances. The whole topic revolves around the scalar (or dot) product. Often we are concerned with perpendicular vectors, and the fact that the scalar product equals zero in this case is a hugely important result. Since problems are often set in 3 dimensions, the ability to visualise the situations or draw a quick sketch can help. Key...
