Answer 1

Answer:

1/2

Step-by-step explanation:

Hii Mate ✌

Its NDA question of this year naa??

I also gave.

1/2 is the answer.

Let me explain you.

Let f(x) = sin x . cos x

            = 2 sin x . cos x / 2

            = sin (2x) / 2

Since, sin x has a maximum value of 1,

So, sin (2x) can take a maximum value of 1,

hence, max value of f(x) = sin (2x) /2 = 1/2

100% CORRECT ✔️✔️

HOPE IT HELPS YOU,
