" 3."sqrt((1-tan x)/(1+tan x))

If y = sqrt((1 + tan x)/(1 - tan x)) " then " (dy)/(dx)= ?

tan^(-1)((sqrt(x)(3-x))/(1-3x))

Solve : 3 tan^(-1) (1/(2+sqrt(3)))-tan^(-1)(1/x) = tan^(-1) (1/3)

"tan^(-1)"((sqrt(x)-x)/(1+sqrt(x^(3))))"

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

int(tan x)/(tan^(2)x+tan x+1)dx=x-(k)/(sqrt(A))tan^(-1)((k tan x+1)/(sqrt(A)))+C, then the ordered pir of (K,A) is equal to : (A) (2,1)(B)(-2,3)(C)(2,3)(D)(-2,1)

Solve tan x+tan2x+sqrt(3)tan x tan2x=sqrt(3)

Solve tan x+tan 2x + sqrt3 tan x tan 2x= sqrt3

int tan^(-1) sqrt x dx=.............a)x tan^(-1) sqrt x - sqrt x + tan^(-1) sqrt x + c b)x tan^(-1) sqrt x + sqrt x - tan^(-1) sqrt x + c c)- x tan^(-1) sqrt x - sqrt x + tan^(-1) sqrt x + c d)x tan^(-1) sqrt x + sqrt x + tan^(-1) sqrt x + c
