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

Solve the differential equation (dy)/(dx)=sec^(2)x .

Solve the differential equation (dy)/(dx)=sec^(2)x .

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

x + y (dy)/(dx) = sec(x^(2) +y^(2)) " when " x =y =0

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

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

x+y(dy)/(dx)=sec(x^(2)+y^(2)), where x^(2)+y^(2)=u
