The video tutorial explains how to find the B coordinates of a vector given its coordinates relative to the standard basis. It covers the concept of transition matrices, their inverses, and how to use them to convert coordinates. The tutorial includes a step-by-step process of finding the inverse of a matrix formed by basis vectors and using it to calculate the B coordinates of a vector. The final result shows the B coordinates of the vector as (-2, 2).
