Airy Functions

The Airy functions are the solutions of the following second order linear differential equation:

Using power series techniques we can derive the following recurrence relation for the coefficients of the power series solution:

Now it is easy to define the partial sums of the two linearly independent power series solutions.

Below we plot some of the partial sums of one of the power series solutions to get an idea of the plot of the convergent series.
