Tensor Analysis (Lecture- 2) ।। Contravariant and Covariant Vectorsbr br Here we start a series of video lectures on Tensors to cover it's full course. This is the second video from this series. In this video some basic concepts about Contravariant & Covariant Vectors are discussed. The following topics are covered in this video ---- br 1.) Why Vector is Tensor of Rank One ?br 2.) Definition of Contravariant & Covariant Vectors and their Transformation Equation.br 3.
