Evaluate the determinant `Delta=|(1,2,4),(-1,3,0),(4,1,0)|`

Evaluate the determinant Delta=det[[1,2,4-1,3,04,1,0]]

Find minor or element 5 in the determinant Delta=|{:(2,4,3),(1,5,2),(-1,4,1):}|

Delta=det[[1,2,4-1,3,04,1,0]]

Evaluate the following determinants by two method : |{:(1,2,4),(-1,3,0),(4,1,0):}|

Consider the determinants Delta=|{:(2,-1,3),(1,1,1),(1,-1,1):}|,Delta'=|{:(2,0,-2),(-2,-1,1),(-4,1,3):}| STATEMENT-1 Delta'=Delta^2 . STATEMENT-2 : The determinant formed by the cofactors of the elements of a determinant of order 3 is equal in value to the square of the original determinant.

Write minors and cofactors of the elements of the determinants: |{:(1,0,4),(3,5,-1),(0,1,2):}|

If x epsilon R the determinant Delta=|(1,cosx,0),(-1,1-cosx,sinx+cosx),(0,-1,1-sqrt(2)sin(x+pi//4))| equals

The cofactor of the element '4' in the determinant |(1,3,5,1),(2,3,4,2),(8,0,1,1),(0,2,1,1)| is

find the value of |{:(1,,2,,4),(-1,,3,,0),(4,,1,,0):}|

In the determinant, Delta = |[-2, 5, -1], [4, 7, 0], [5, -3, 1]|, the sum of the minors of elements of third row is
