Vector rotation
Analysis and understanding
Analysis of each quadrant process are as follows:
In the first quadrant, for example, the vibration velocity of each analysis positive and negative quadrants: the
first approach is: starting from the defined speed. The analysis of the above figure.
The second method is: the speed vector decomposition.
As shown in: p separable point velocity drop velocity component (negative direction) horizontally leftward.
A third approach is to: cut by decision type, that can be easily understood based on derivation formula in the figure below.

Q: is the particle vibration left image, right is the rotation vector corresponding, left in Q, T, S, respectively, in which three points in the right panel corresponds 1,2,3,4?
A: Slightly.
For the answer can be private letter or a message. - physics, infinite mystery.
Mathematical knowledge, all ideas proceed from the definition of
