Vector Algebra

This topic talks about the basic definition of a vector, terminologies such as the initial point, terminal point and the magnitude. It introduces the concept of a position vector and direction cosines and provides formulas for each.

This topic explains the parallelogram law that is used for adding the vectors. It also explains the triangle law of addition of vectors through illustrations.

This topic discusses the multiplication of vectors by a scalar and their representation through an equation. It also explains the properties and theorem to prove the equations through examples here.

This topic states that multiplication of two vectors is done in two ways namely scalar or dot product where the result is a scalar and vector or cross product where the result is vector. It also includes projection of a line using illustrations.
