- Various Coordinate Systems
- Cartesian Coordinates
- The vectors form a basis.
- It is trivial that they are orthogonal to each other.
- In Polar Coordinates, similar Basis Vectors can be defined.
- It is difficult to grasp intuitively.
- However, they still form an Orthogonal Basis (the basis vectors are orthogonal to each other).
- Regardless of the chosen coordinate system, physics remains the same.
