Hey All,
Can someone please give me the gist of how to show that the integral form of the Airy function for real inputs:
[tex]
Ai(x) = \frac{1}{\pi} \int_0^\infty \cos\left(\tfrac13t^3 + xt\right)\, dt,
[/tex]
satisfies the Airy Differential Equation: y'' - xy = 0
I tried differentiating twice wrt to the x variable (assuming I could just bring it inside the integration) and then subbing back into the ODE but that failed.
Regards,
Thrillhouse
