The given 3 li vector that is u is equal to 3, negative 1, 6, v is equal to 6, 2, negative 7 and w is equal to 9, 1, negative 1.
00:23
So to find the determinant of matrix formed by u, v and w.
00:47
So the matrix a, place all the vector in the column that is 3, negative 1, 6, 6, 2, negative 7, 9, 1, negative 1.
01:03
So determinant of a is equal to 3 multiplied to 2, 1, negative 7, negative 1, negative 6, determinant of negative 1, 6, 1, negative 1 plus 9, the determinant of negative 1, 2, 6 and negative 7...
