Spletmal basis of V, B 2 = (f 1;:::;f m) be an orthonormal basis of W, and let T: V !W be a linear map. Then the matrix A of T with respect to B 1 and B 2 is given by a ij= hTe j;f ii: Proposition 1.10. Let V be an inner product space, B an orthonormal basis of V, and T : V !V a linear map. Then T is a unitary map if and only if the matrix of T with Spletbasis of its transformation matrix. Symmetric, positive definite matrices always have positive, real eigenvalues. determinant, trace, eigenvalues: all invariant under basis change. Examples for Geometric Interpretation (1) A = (1 2 0 0 2), det(A) = 1 λ 1 = 1 2 , λ 2 = 2 eigenvectors: canonical basis vectors
