EXAMPLES OF PROOFS BY INDUCTION

WebProof by induction − Here we start with a specific instance of a truth and then generalize it to all possible values which are part of the truth. The approach is to take a case of verified truth, then prove it is also true for the next case for the same given condition. For example all positive numbers of the form 2n-1 are odd. Web3 Matrix Norms It is not hard to see that vector norms are all measures of how \big" the vectors are. Similarly, we want to have measures for how \big" matrices are. We will start with one that are somewhat arti cial and then move on to the important class of induced matrix norms. 3.1 Frobenius norm De nition 12.
