Vedclass · Answer

(B) Let $f(x) = \sin (\cos (	an x))$.We know that the range of the function $	an x$ is $(-\infty, \infty)$.Therefore,the range of $\cos (	an x)$ is $[-1, 1]$.Let $u = \cos (	an x)$,where $u \in [-1, 1]$.Then the function becomes $g(u) = \sin u$ for $u \in [-1, 1]$.Since $\sin u$ is an increasing function on the interval $[-1, 1]$,the maximum value occurs at the maximum value of $u$.The maximum value of $u$ is $1$.Thus,the maximum value of the function is $\sin(1)$.

The maximum value of $\sin (\cos (\tan x))$ is
