    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.
