Consider tje differential equation xy'-4x^2y+2ylny=0
(a)Show that the substitution v=lny transforms the differential equation into
a linear differential equation.
(b)Find y(x)=?
(c)Find an integrating factor ρ(x,y) so that the multiplication of the
differential equation by ρ(x,y) yields an exact differential equation.
(c)問題看得不是很懂，有誰可以幫幫忙的嗎?謝謝^^
