The video tutorial explains the concept of a transformation T, its properties, and conditions for invertibility. It discusses the identity transformation and proves that T-inverse is a linear transformation. The tutorial also covers the matrix representation of T-inverse and its relationship with the identity matrix.

What does it mean for a transformation T to be invertible?

• It is a non-linear transformation.

• It can be represented as a matrix.

• Its transformation matrix can be reduced to an identity matrix.

• It maps from Rn to Rn.
