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

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

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