Hi everyone. Aftrer doing a search I found loads of information but I still cant get my head around these damm vectors. I understand the basics and how to work out the dot product if given the question in a given way. An example of the questions im being asked are: The following two vectors are: p = 4i + 3j - 2k and q = 2i - 4j - 3k i) Find p+ q ii) Find p – q iii) Find the scalar product of pq iv) Find the direction cosines for both p and q v) Find the angle between vectors p and q, giving your answer to 2 decimal places (d.p.) When the vectors are written in this form I literally dont know where to start! Any help would be much appreciated. Thanks.
