Which one of the following determinants has its value as zero?
If 1, ω , ω2 are the cube roots of unity, then
0
1
ω
ω2
The value of the determinant is
(a - b) (b - c) (c - a)
None of these
If each entry in any row, or each entry in any column of a determinant is 0, then the value of the determinant is equal to
3
-1
, then
Δ = 0
Δ = 2 abc
Δ = -abc
Δ = a2 + b2 + c2
∞
then f (x) is divisible by
n2 + n
(n + 1)!
(n + 2)!
n! (n2 + n + 1)
2
-2
