A Way To Store Vectors We already know how to play around with vectors on 2D paper. We can draw them and make constructions. In the previous chapter we saw that it's possible to decompose vectors and to make linear combinations. If you look closer, you can see that it should be possible to create each free 2D vector with a linear combination of those same 2 vectors U and V .
V equals that vector.
You can do that with almost every pair of vectors like U and V . A pair of vectors you use to create all other vectors in your space, is called a base . We call both vectors the base vectors , and normally we call those base vectors I and J . As you can see we use bold italic capitals for that. We see that I and J are the 2 base vectors inside B .
