Answer (1 of 4) Step 1 The trick is to make the change of (independent) variable t = ln x, to reduce the equation to a linear differential equation with constant coefficients, which presumably you already know how to solve Then x = e^t and dt/dx = 1/x If you are careful with the product rule #(k3)(k2)a_(k3)(k1)a_k=0# for #k = 0,1,2,3, cdots# This infinite recurrence equation needs the a priori definition of #a_0, a_1# which can The basic idea to finding a series solution to a differential equation is to assume that we can write the solution as a power series in the form, y(x) = ∞ ∑ n=0an(x−x0)n (2) (2) y ( x) = ∑ n = 0 ∞ a n ( x − x 0) n and then try to determine what the an a n 's need to be
