```										Dear anuj,

Let's say we have two vectors, A and B, as shown to the left.  The  values |A| and |B| represent the lengths of vectors A and B, respectively, and Θ is the angle between the two vectors.   The dot product of vectors A and B will have the following relationship to these  values:
A · B = |A| * |B| * cos(Θ)
That is to say, the dot product of two vectors will  be equal to the cosine of the angle between the vectors, times the lengths of  each of the vectors.

We are all  IITians and here to help you in your IIT  JEE preparation.  All the best.
