Expand description
Airy functions Ai(x) and Bi(x) via their Maclaurin series. Accurate for moderate
|x| (the series converge for all x but lose digits for large argument).
Ai = α·f − β·g, Bi = √3·(α·f + β·g), where α = Ai(0) = 3^{-2/3}/Γ(2/3),
β = −Ai'(0) = 3^{-1/3}/Γ(1/3), and f, g are the two hypergeometric series.
