The value of `int tan x dx` is-

Obtain reduction formula for l_(n)=inttan^(n)xdx , n being a positive integer n le 2 and deduce the value of int tan^(6)x dx .

Evaluate : int tan x dx .

The value of int (tan x )/(tan ^(2) x + tan x+1)dx =x -(2)/(sqrtA) tan ^(-1) ((2 tan x+1)/(sqrtA))+C Then the value of A is:

The value of int (tan x )/(tan ^(2) x + tan x+1)dx =x -(2)/(sqrtA) tan ^(-1) ((2 tan x+1)/(sqrtA))+C Then the value of A is:

The value of int (tan x )/(tan ^(2) x + tan x+1)dx =x -(2)/(sqrtA) tan ^(-1) ((2 tan x+1)/(sqrtA))+C Then the value of A is:

The value of int (tan (log x))/(x)dx is-

The value of int {1+tan x*tan (x + A)}\ dx is
