(ii) If the relation R = { (1, 2), (2,1), (1, 3), (3, I)} defined on the setA = {1, 2, 3}, then R is. (iii) If the relation R on the set N of all natural numbers defined as R = { (x, y) : y = x + 5 and x < 4}, then R is. (iv) If the relation R on the set A ... WebThe determinant will be equal to the product of that element and its cofactor. In this case, the cofactor is a 3x3 determinant which is calculated with its specific formula. Example 33 $\begin{vmatrix} 1 & 3 & 9 & 2\\ 5 & 8 & 4 & 3\\ 0 & 0 & 0 & 0\\ 2 & 3 & 1 & 8 \end{vmatrix}$ We notice that all elements on row 3 are 0, so the determinant is 0.
If the points $(3,-2)$, $(x,2)$ and $(8,8)$are collinear, then find the ...
WebWeb The value of determinant of order three can be in the terms of minors and cofactors can be defined as. The sum of products of elements of row column of the determinant on the cofactors to the elements of other row column is equal to zero. A different type of cofactor sometimes called a cofactor matrix is a signed version of a minor defined by.
