## Main Question or Discussion Point

Hello!

I have difficulty to solve a PDE. I'm trying to simplify the third order eq. into the second order Airy equation. But I can't see where I could start. Could you, please, help me.

Where should I start?

Equations is:

[tex]

\frac{\partial^{3}F(x,y)}{\partial y^{3}}-ix(y+C)\frac{\partial F(x,y)}{\partial y}=0

[/tex]

where C is positive constant [tex] i=\sqrt{-1} [/tex]

Thank You.
