`int sec x(sec x+tan x)dx`

int sec x ln(sec x+tan x)dx=

If int e^(sec x)(sec x tan x f(x)+(sec x tan x + sec^(2) x))dx = e^(sec x)f(x) + C , then a possible choice of f(x) is

int sec x (sec x + tanx ) dx =

int(sec x)/((sec x+tan x)^(2))dx

int sec x log (sec x+tan x) dx.

Evaluate: (i) int sec x log(sec x+tan x)dx (ii) int cos ecx log(cos ecx-cot x)dx

int e^(x)sec x(1+tan x)dx

evaluate int e^(x)(sec x+sec x tan x)dx

Evaluate: int e^(x)[(sec x+log(sec x+tan x)]dx

int (sec x+tan x)tanx dx
