Dot product and equation of a plane.

Description
Dot product of a vector is defined and explained and is represented geometrically. What does the geometrical definition of dot product mean is explained. Application of vector dot product is shown. Equation of a plane is discussed. The use of dot product in Physics is also explained. How to calculate components of vectors in certain direction is also discussed here.
