a) Given a square matrix A, describe a computational algorithm to determine whether A is invertible, . if so, find its inverse matrix. b) Then explain why we can trust the results to be correct - even if we don't trust computers. (You can use notions and cite facts/theorems from WorkScripts 0-7 for this. Any other theorems/facts would require complete proof.) Feel free to use examples, but know that we are looking for generally applicable explanations.
