Dear Nimisha,

well the value of cos decreases with the increase in value of x from 0 to 90 degrees,

so cosx is minimum at x =                          . its value will be 0.

so cos(cosx) = cos(0) = 1.

this is the amximum value.

the max value of cosx is 1 at x = .

so minimum value of cos(cosx) = cos1.
