If `y=tan^(-1)(cos x)`,then the value of "`(dy)/(dx)`=

If y=tan^(-1)((cos x+1)/sinx) ,then the value of " (dy)/(dx) =

y=[(1-tan x)/(1+tan x)], then the value of (dy)/(dx)

If y = log(tan sqrt(x)) , then the value of (dy)/(dx) is

If y=log sin x+tan x, then Find the value of (dy)/(dx)

If y=tan^(-1)sqrt((1-sin x)/(1+sin x)), then the value of (dy)/(dx) at x=(pi)/(6) is.

Find y=e^(sqrt(tan x)) then find the value of (dy)/(dx)

If y = tan^(-1){(cos x)/(1 + sinx)} " then " (dy)/(dx) = ?

if y=tan^(-1)((cos x)/(1+sin x)) then (dy)/(dx)

If y = tan^(-1) ((1 - cos x)/(sin x)) " then "(dy)/(dx)= ?

If (cos^(4)alpha)/(x)+(sin^(4)alpha)/(y)=(1)/(x+y) then prove that the value of (dy)/(dx) is tan ^(2)alpha
