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

x sec x tan x

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

If tan y=(tan x+sec x-1)/(tan x-sec x+1) show that (dy)/(dx)=(1)/(2)

If tan y=(tan x+sec x-1)/(tan x-sec x+1), " show that, " (dy)/(dx)=(1)/(2) .

If tan y = (tan x+sec x-1)/(tanx -sec x+1) show that (dy)/(dx) = 1/2

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

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

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

Expression (tan x)/(1 + sec x)- (tan x)/(1 -sec x) is equal to:
