int sec x tan x sqrt(tan^(2) x-4) dx

int sec x tan x sqrt(tan^(2) x-4) dx

tan x sqrt( sec x )

"Sec" (tan sqrt(x)) .

Evaluate: int tan x sec^(2)x sqrt(1-tan^(2)x)dx

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

sqrt(2)sec x+tan x=1

int sec^(2)x sqrt(tan^(2) x+tan x-7)dx

tan x+sec x=sqrt(3)

(sec x sec y + tan x tan y) ^ (2) - (sec x tan y + tan x sec y) ^ (2) = 1 Prove it
