Tensor Analysis (Lecture- 2) ।। Contravariant and Covariant Vectors

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 ----
1.) Why Vector is Tensor of Rank One ?
2.) Definition of Contravariant & Covariant Vectors and their Transformation Equation.
3.) Why Velocity and Acceleration are Contravariant Vectors and Gradient of a Scalar field is a Covariant Vector?
