Maxima Function
airy_ai (x)
The Airy function Ai, as defined in Abramowitz and Stegun, Handbook of Mathematical Functions, Section 10.4.
The Airy equation diff (y(x), x, 2) - x y(x) = 0 has two
linearly independent solutions, y = Ai(x) and y = Bi(x).
The derivative diff (airy_ai(x), x) is airy_dai(x).
If the argument x is a real or complex floating point
number, the numerical value of airy_ai is returned
when possible.
