"The only way it could leave would be on some sort of vector."
A set of 48 such vectors is called a frame.
We're making a sort of vector from our course, but the deviation is very small.
The inner product of two vectors is a complex number.
The comparison of local vectors at different places is easy in flat space.
A basis is just a set of vectors with no given ordering.
File size increases only with the addition of more vectors.
Thus, A is seen to be a difference of two vectors with equal time derivatives.
It can be represented as a finite set of vectors.
A vector field is an arrangement of vectors over an area.
