Question
Problem 2. Consider the initial value problem
y" – ty' – y = 0, y(0) = 1, y'(0) = 0.
Since the coefficient functions are all analytic, we can assume the solution to this IVP can
be expressed as a power series:
y()-Σαμt",
y(t) =
Ant".
n=0
(a) Find the coefficients ao, a1, a2, a3, and a5 of the series for y(t).
(b) Find a closed-form expression for the series. That is, look for a pattern in the coeffi-
cients you found in part (a), and write down a general formula for the nth coefficient
in terms of n. What function does this series represent?
