a vector is simply an arrow that contains the following:
- direction (angle)
- magnitude (length).
when you express it onto a cartesian-plane, it gets two vector components:
- x-component (
x') - y-component (
y')
how many x’ and how many y’ to reach tip of a vector in x, y space.
part of a larger group of things called tensors.
