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

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)

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

If x=a(costheta+log"tan"(theta)/(2)) and y=asin theta , then find the value of (dy)/(dx) at theta=(pi)/(4) .

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

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

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

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)

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