tan^(-1)(sec x+tan x)=?

x sec x tan x

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

Prove that (1)/(sec x-tan x)+(1)/(sec x+tan x)=(2)/(cos x)

What is the simplified value of [ ((sec^(3)x - tan^(3)x ))/((sec x - tan x ))]-2 tan^(2)x - sec x tan x ?

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

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

differentiate (sec x-tan x)/(sec x+tan x)

Is (sec x + tan x + 1)(sec x - tan x - 1) - 2tan x = 0 an identity.
