Different types of complex algebra methods are :

1) Velocity and acceleration analysis by complex variable method

2) Loop closure equation

- The relation between position vectors of different links in a mechanism is given by loop closure equation.

- According to loop closure equation, in a closed loop mechanism the sum of relative position vectors for a link is always zero.

- The magnitude of relative position vectors do not change with time even if loop changes its position, because joints of the links are always fixed at a distance from each other.
