Web Everything I did so far was in R2 But I want to show you that we can generalize them And we can even generalize them to vector spaces that aren t normally intuitive for us to actually visualize So let me define a couple of vectors Let me define vector a to be equal to 0 minus 1 2 and 3 Let me define vector b to be equal to 4 minus 2 0 5
