I have two ODE with which I cannot to slove;(adsbygoogle = window.adsbygoogle || []).push({});

3x^{2}ydx+(x^{3}+2y)dy=0

I tried to change of variable y=v*x, but I still cannot find a way to solve it.

the second is:

(e^{x}sin(y)-2ysin(x))dx+(e^{x}cos(y)+2cos(x))dx=0

here I have no idea

thank you
