sec^(p)x tan x

Ify=( sec x^(@) +tan x^(@))/( sec ^(@) -tan x^(@) ) ,then (dy)/(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 ?

lim_(x rarr0)((x+y)sec(x+y)-x sec x)/(y) is equal to sec x(x tan x+1)(b)x tan x+sec xx sec x+tan x(d) none of these

Evalute the following integrals int (sec^(2) "x tan x")/(sec^(2) x + tan^(2) x) dx

Evaluate: (i) int(tan x sec^(2)x)/((a+b tan^(2)x))dx (ii) int sec^(3)x tan xdx

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

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

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

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
