## Airy Functions and Derivatives

The Airy functions Ai(x) and Bi(x) are defined by the integral representations,

    Ai(x) = (1/\pi) \int_0^\infty \cos((1/3) t^3 + xt) dt
    Bi(x) = (1/\pi) \int_0^\infty (e^(-(1/3) t^3) + \sin((1/3) t^3 + xt)) dt

For further information see Abramowitz & Stegun, Section 10.4. The Airy functions are defined in the header file ``gsl_sf_airy.h'`.
