The Airy wave functions AiryAi and AiryBi are linearly independent solutions for w in the equation $w\text{'}\text{'}-zw=0$. Specifically,

where ${}_{0}F_1$ is the generalized hypergeometric function, $c_1=\mathrm{AiryAi}\left(0\right)$ and $c_2=-\mathrm{AiryAi}\'\left(0\right)$.

The two argument forms are used to represent the derivatives, so AiryAi(1, x) = D(AiryAi)(x) and AiryBi(1, x) = D(AiryBi)(x). Note that all higher derivatives can be written in terms of the 0'th and 1st derivatives.

Note also that $\mathrm{AiryAi}\left(3\,x^2\right)$ is the 3rd derivative of $\mathrm{AiryAi}\left(x\right)$ evaluated at $x^2$, and not the 3rd derivative of $\mathrm{AiryAi}\left(x^2\right)$.

The Airy functions are related to Bessel functions of order $\frac{n}{3}$ for $n=\mathrm{-2},\mathrm{-1},1,2$ (see the examples below).
