Consider it a bridge between different bases.
What does matrix similarity indicate?
Recall the definition of matrix similarity.
True or False: The change-of-basis matrix must be singular.
Think about what singular means in terms of matrix transformations.
Given matrices A and B, show through an example how to find a change-of-basis matrix P that satisfies B = P⁻¹AP.
Start with finding the eigenvalues using the characteristic polynomial.
