Question

Maximum value of sin(cos(tanx)) is

(1) sint (2) 3. (3) sin(cos 1)​

Answer 1

Answer:

Sin1

Step-by-step explanation:

Maximum value of sin(cos(tanx)) is

Tan x can have value from -∞ to +∞

Cos(tanx) has range from -1 to 1

So

Sin(cos(tanx)) will has range  

Sin(-1)  to Sin (1)

Sin(-1) will have -ve Value

Sin 0 = Sin0°

Sin 1  = Sin57.32°

From 0 to 90° Sin Increases

Hence Sin57.32° is Max

=> Sin1 is Maximum value of sin(cos(tanx))
