If a determinant of order `3xx3` is formed by using the numbers 1 or -1 then minimum value of determinant is :A. -2B. -4C. 0D. -8 |
|
Answer» Correct Answer - B `|{:(1-2 sin^(2)x,,sin^(2)x,,1-8 sin^(2)x(1-sin^(2)x)),(sin^(2)x,,1-sin^(2)x,,1-sin^(2)x),(1-8sin^(2)x(1-sin^(2)x),,1-sin^(2)x,,1-sin^(2)x):}|` The required constant terms is `|{:(1,,0,,1),(0,,1,,1),(1,,1,,1):}|+|{:(1,,0,,0),(0,,1,,1),(1,,1,,0):}|=1(10 -1)=-1` |
