first order DE

**tjkubo** · January 31st 2010, 10:57 AM

I have no clue what to do to solve this since it isn't separable and I can't find an integrating factor. I know y=0 is a solution by guessing, but that's all I have so far.
$<br /> (e^xsin y+3y)dx-(3x-e^xsiny)dy=0<br />$

Hi , I dont really know how to solve this but I notice it almost looks like exact equation...

That's all I got, sorry

Equation is of the form
$M(x,y)dx+N(x,y)dy=0$
Then you can solve.
