y=log sqrt(tan x),(dy)/(dx)" at "x=(pi)/(4)

y= log sqrt(tan x) , find (dy)/(dx) at x= (pi)/(4)

If y=[(tan x)^(tan x)]^(tan x)," find " (dy)/(dx)" at " x=(pi)/(4) .

If y=log sqrt(tan x), write (dy)/(dx)

If y=log_(sinx)(tanx), then (dy)/ (dx) at x=(pi)/(4) is equal to

If y=log_(sinx)(tanx), then (dy)/ (dx) at x=(pi)/(4) is equal to

If y=log sqrt(tan x), then the value of (dy)/(dx) at x=(pi)/(4) is given by oo(b)1(c)0(d)(1)/(2)

If y=log tan((pi)/(4)+(x)/(2)), show that (dy)/(dx)=sec x. Also find the value of (d^(2)y)/(dx^(2)) at x=(pi)/(4)
