SUMMARY
This discussion focuses on the relationship between linear transformations and matrix representations in different bases. Specifically, it addresses the challenge of determining the new basis \( v \) given a matrix \( A \) in basis \( u \) (denoted as \( A_u \)) and its representation \( A_v \) in an unknown basis. The consensus is that it is generally impossible to find the new basis \( v \) solely from the information provided, as demonstrated by the identity matrix, which retains its form across all bases.
