In physical and geometry there are quantities each of which is completely specified when its magnitude that is, its size or number of units according to some scale is given. Examples are the mass of body, the charge of an electron, the specific heat of water, the diameter of circle, each of these quantities is described by a single number (after a suitable choice of units of measure). Such a quantity is called a scalar. However, there are other physical and geometrical quantities which cannot be described by a single number, because they required the specification of a direction as well as a magnitude.In this chapter we will define many types for treatment with vectors application.we will study the dot product and cross product with calculated the distance btween two vectors or planes or any point with line and plane.the line equation in plane and space will found using vectors method and many problem that have relation with vectors.The line equation in space need parallel vector with point on this line while, the line in plane need normal vector with point.
