Given, two vectors A and B. 

That is, the angle between the resultant of two vectors is, 
 
                     tan to the power of negative 1 end exponent open parentheses fraction numerator straight B space sinθ over denominator straight A plus straight B space cosθ end fraction close parentheses

Two vectors of magnitude A and B are acting at angle straight theta. What is the magnitude of resultant?


The magnitude of the resultant vector is given by, 

                      square root of straight A squared plus straight B squared plus 2 AB space cosθ. end root

What is the composition of vectors?

The process of compounding two or more vectors into a single vector is called composition of vectors.

Composition of vectors determines the resultant of two or more vectors.
