EDITED (to change cos to sin)

Solution seems to be
$$\eqalign{\dfrac{\Gamma(2/3)\; 3^{2/3}}{8} &amp; \left((-\sqrt{3}+i) e^{-ix} Ai(-(\sqrt{3}+i)y/2) \right.\cr
&amp;  - (\sqrt{3} + i) e^{ix} Ai(-(\sqrt{3}-i)y/2) \cr
&amp;  + (\sqrt{3} i + 1) e^{-ix} Bi(-(\sqrt{3}+i)y/2)\cr
&amp; + \left. (-\sqrt{3} i + 1) e^{ix} Bi(-(\sqrt{3}-i)y/2)   \right)\cr}
$$
where $Ai$ and $Bi$ are Airy functions.

Analytical solution to PDE
Is there a way to cause google-chrome to quit, from the terminal, besides using killall google-chrome? 
I would like to be able to close it from a script without killing it.
