For the differential equation (2) (a) Use the Successive Differentiation Method to find the first six nonzero terms in the power series expansion, ant", of the general solution of (2). (b) Find the recursion formula and use it to find the first six nonzero terms in the power series expansion, o ant of the general solution of (2). HINT: You may want to use the following: =0 Theorem 1. If p(t) = d'y dt d'y dt has a unique solution 71=0 for It-tole, then the initial value problem dy +p(t)+q(t)y = 0, dt an+2 = + e'y=0 p.(t-to)" and g(t) = [qn(t-to)" n=0 with an, n 2, satisfying the recurrence relation 71 1=0 y(to) = ao, y'(to) = a, y(t) = [an(t-to)" 1 (n + 2)(n+1) k=0 The series no an(t-to)" converges for It-tol < . n=0 [(k+1)pn-kak+1+qn-kak], n 0.
