Question: For the matrix 2 2 1 0 1 0 1 3 1 3 0 2 0 0 4 2 a) Compute the determinant By DEFINITION,

For the matrix

2210101313020042

a) Compute the determinant By DEFINITION, write out all the permutations and all the products.

b) Now compute the determinant by row-reducing it to a triangular matrix.

c) Now compute the determinant a third time by cofactor expansion along column 3. Obviously, answer for part a, b, and c should all be the same.
