1. cp+dr aq+bs cq+ds 2. cp+dr aq+bs cq+ds aq+bs=0 cp+dr=0 cq+ds=1 3. -c -b a 4. -b a -c 5. ad-bc -c -b a 6. Discussion: a) the scalar is 1 position of a and a are exchanged while b and c are multiplied by -1. 7. Conclusiona) 1 ad-bc d a -c -b b) Determinant for matrix A, IAI is ad-bc, where ad-bc≠0.Therefore inverse matrix exist.Inverse matrix does not exist when ad-bc=0.
