`int(1)/(1+sec x)dx`

int (dx)/(sec x)

(i) int(tanx)/((sec x +tanx))dx , (ii) int(1)/((1-sinx))dx

I= int(1)/(sec x-tan x)dx

Ecaluate the following: (i) int(sec^(2)x)/(3+tanx)dx " (ii) " int(e^(x)-e^(-x))/(e^(x)+e^(-x))dx (iii) int(1-tanx)/(1+tanx)dx " (iv) " int(1)/(1+e^(-x))dx

int sqrt(1+sec x)dx

int_(0)^((pi)/(3))(x)/(1+sec x)dx

int(tan^(2)x)/(sec x-1)dx

int(sec x)/(1+csc x)dx

int(tan x+sec x-1)/(tan x-sec x+1)dx

Evaluate: int(1+tan x)/(x+log sec x)dx
