Understanding Vector Coordinates and Transition Matrices

The video tutorial explains how to find the coordinates of vector W relative to a new basis B, given its coordinates in the standard basis. It covers the concept of transition matrices, their inverses, and how to use them to transform vector coordinates. The process involves calculating the inverse of a 3x3 matrix formed by basis vectors and using it to find the new coordinates. The tutorial concludes with the final coordinates of vector W in basis B.
