We first consider the vector transformation from the coordinate system
**K** to the co-rotational system **K'**.
The pointer vector is represented by
the linear combination of the unit vector ()
in **K**:

in the co-rational system

where is the angler velocity vector. When the differential operator is applied in equation (2), the relation (3) above gives

Here the first term in the right hand side above is the velocity seen by the observer in the co-rational system

where is the velocity vector.

The acceleration in **K** is then obtained
by the time differential of the equation (4)
as

Here we used the relation (3). The first term in the right hand side in the equation above represents the accelerator for the observer in
