(a) Assume | → | | |→ → | (b) |→ | | | | |→ | . For
the value of det is zero which means
You can check the truth by plugging in the values and using Matlab/Octave. . Problem 3.
a. Row operations don’t change the determinant of a matrix. The resulting matrix is: |
| b. The resulting matrix is:
| c. The resulting matrix is lower triangular hence: |
| Problem 4.
(a) The corresponding matrix equation is:
This system has a unique solution iff
[ ] . Hence: | which always holds. Using Cramer’s Rule: ....
