Prove or give a counterexample:
ozzi

Answer:

See proof below.

Step-by-step explanation:

True

For this case we need to use the following theorem "If v_1, v_2,....v_k are eigenvectors of an nxn matrix A and the associated eigenvalues \lambda_1, \lambda_2,...,\lambda_k are distinct, then v_i's are linearly independent". Now we can proof the statement like this:

Proof

Let A a nxn matrix and we can assume that A has n distinct real eingenvalues let's say \lambda_1, \lambda_2, ....,\lambda_n

From definition of eigenvector for each one \lambda_i needs to have associated an eigenvector v_i for 1 \leq i \leq n

And using the theorem from before , the n eigenvectors v_1,....,v_n are linearly independent since the \lambda_i 1\leq i \leq n are distinct so then we ensure that A is diagonalizable.
