(b)sqrt((1-tan x)/(1+tan x))

If y = sqrt((1 + tan x)/(1 - tan x)) " 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) =

tan^(-1)((a+b tan x)/(b-a tan x))

int(1)/(1-sin^(4)x)dx=(1)/(a sqrt(b))+tan^(-1)(sqrt(a)tan x)+(1)/(b)tan x+C then (a)/(b) is equal to

If int (sqrttanx + sqrtcotx) dx = a tan^-1 ((tan x - 1)/sqrt(b tan x)) + c , then the value of sqrt(a^4 + b^5) must be
