If 0 < K < 1 which of the following has thehighest value?

$1/{√{2\k+1$
$1/{\k+2$
$1/\k^2$
$1/√\k$

Solution:

(c) Let the value of K =

1/2\;\;\;\;\;\;\;\;\;\;\;\;\;\{\given 0<\k<1\}

Then, (a)

1/{√{2\k+1 }}= 1/√2

= 0.707
(b )

1/{\k+2 } =1/{1/2+1} = 2/3 =0.40

(c )

1/\k^2 = 1/(1/2)^2 = 4

(d)

1/√\k =√2 = 1.414

⇒ Hence,

1/\k^2

has the highest value.
