" 6."(dy)/(dx)=sec^(2)x+4x

Find (dy)/(dx) , when If y = (cos x + sinx)/(cos x - sinx) , show that (dy)/(dx) = sec^(2) (x + (pi)/(4)) .

x(dy)/(dx)-y=2x^(2)sec x

(dy)/(dx)+y tan x=sec x

(dy)/(dx)+y sec x=tan x

Write integrating factor differential equations (dy)/(dx)+y sec^2 x = sec x +tan x

The solution of (dy)/(dx) = sec(x+y) is

Find (dy)/(dx) , when If y = sqrt((sec x - tanx)/(sec x + tanx)) , show that (dy)/(dx) = sec x (tanx - sec x) .
