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

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

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

int(1)/(7+5cos x)dx=(1)/(sqrt(6))tan^(-1)((1)/(sqrt(6))(tan x)/(2))+C(b)(1)/(sqrt(3))tan^(-1)((1)/(sqrt(3))(tan x)/(2))+C(c)(1)/(4)tan^(-1)((tan x)/(2))+C(d)(1)/(7)tan^(-1)((tan x)/(2))+C
