" (iii) "y=a sec x+b tan x

Eliminate a and b, y = a sec x + b tan x

Find (dy)/(dx) : y = a sec x +b tan x - c cosec x + d cot x - e

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

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

if x = a sec theta + b tan theta y = b sec theta + a tan theta then x^(2) - y^(2) is equal to

Eliminating theta from the following (ii) x = a ( sec theta + Tan theta), y = b (sec theta - tan theta)

The solution of the differential equation cos y log (sec x + tan x)dx=cos x log(sec y + tan y)dy is

The solution of cos y log (sec x + tan x)dx = cos x log (sec y + tan y) dy is

If y = tan^(-1) (sec x + tan x) " then " (dy)/(dx)= ?
