Vector Subtraction

Given vectors A and B as follows:



The parallelogram for vector subtraction takes the following form:





Resolution of a Vector

A vector may be resolved into to components having known lines of action using the parallelogram law:

Given the vector R below:



Extend parallel lines from the head of vector R to form components in a and b axis



The resolution of vector R into vector A and vector B is as follows:
