|2x -3| < | x + 5 |, then x belongs to :
( -3, 5 )
( 5, 9 )
( -2/3, 8 )
( -8, 2/3 )
( x - 1 ) > 0
( x -2 ) > 0
(x - 2 ) < 0
( x - 1 ) > 0 if ( x -2 ) > 0
If 3 < | x | < 6, then x belongs to _______.
( - 6, -3 ) U ( 3, 6 )
( - 6, 6 )
( -3, -3 ) U (3, 6 )
None of these
As sinx < x and x < tanx in ( 0,π/2 ), so in the same interval
Sinx < tanx
Sinx > tanx
sin2 x > tan 2 x
|sinx | > |tanx |
If a < b then,
a/(-2 ) < b/(-2)
a/2 > b/2
1/a < 1/b
a/-2 > b/-2
If |x| > 5, then
0 < x < 5
x < -5 or x > 5
-5 < x < 5
x > 5
( x2 + 1 ) (x - 1 ) ( x -2 ) < 0 , then
x < 1 or x > 2
x ∈ ( 1, 2 )
-1 < x
|x + 2/x | < 3, then x belongs to ________.
(-2,-1) U ( 1,2 )
(-∞, -2 ) U (-1, -1) U ( 2, ∞ )
(-2, 2 )
(-3, 3 )
x2 -3 |x| + 2 < 0, then x belongs to ________.
( 1,2 )
( -2, -1 )
( -2, -1 ) U ( 1, 2 )
If a > b then
2a > 2b
|2a | > | 2b |
-5a > -5b
