Find two power series solutions of the given differential equation about the ordinary point x=0. WebSep 5, 2024 · Instead, we use the fact that the second order linear differential equation must have a unique solution. We can express this unique solution as a power series. y = ∞ ∑ n = 0anxn. If we can determine the an for all n, then we know the solution. Fortunately, we can easily take derivatives. y ′ = ∞ ∑ n = 1nanxn − 1. tsh goven
