Dear students from MAT223:
I’ve received some requests to explain the following questions and I made a few short videos to explain how to solve them.
- If and are linear transformations , and are three distinct vectors in so that
then for all
2. If A is matrix and dim(null(A-I))=3, then A is diagonalizable.
Decide whether A is diagonalizable. Justify your answer.
4. What is the matrix of a linear transformation
Compute the rank of this matrix.
