If y=log sqrt((1+tan x)/(1-tan x)), Prove that (dy)/(dx)=sec2x

Differentiate sqrt((1-tan x)/(1+tan x)) w.r.t.x

If y=log sqrt((1-tan x)/(1+tan x)), prove that (dy)/(dx)=sec2x

If y=sqrt((1+tan x)/(1-tan x)) then (dy)/(dx)= is equal to

If y= sqrt ((1-tan 2x ) /( 1+tan 2x )) ,then (dy)/(dx) =

lim_(x rarr0)(sqrt(1+tan x)-sqrt(1-tan x))/(sin x)=

If y = tan^(-1) {(x)/(1 + sqrt(1 - x^(2)))} + sin { 2 tan^(-1) sqrt((1 - x)/(1 + x))}, "then" (dy)/(dx) =

Evaluate : int sqrt(tan x) (1+ tan^(2)x)dx
