  • Let y = ∞ ∑ n=0cnxn, where cn is to be determined. By taking derivatives term by term, y' = ∞ ∑ n=1ncnxn−1 and y'' = ∞ ∑ n=2n(n −1)cnxn−2 So, y'' = y becomes ∞ ∑ n=2n(n − 1)cnxn−2 = ∞ ∑ n=0cnxn. Let us solve the differential equation y'' = y by Power Series Method. How do you find a Power Series solution of a differential equation?
    • However, in doing this, the series now starts at n = 1 not n = 0. Well for your first example, in the last step the 1 5 is multiplied into the summation giving the term x n + 1 5 n + 1 (n + 1). Was that a typo? Then the power series is shifted by replacing n with n-1 (which explains the term you have written in the last step). 6 and Example First, we state Note, which provides the main result regarding differentiation. Bing helps you turn information into action, making it faster and easier to go from searching to doing. . Find more information on differentiating power series examples on Bing. l n (5 − x) = − ∫ 1 5 − x d x = − 1 5 ∫ 1 1 − x 5 = − 1 5 ∫ [ ∑ 0 ∞ (x 5) n] d x = C − 1 5 ∑ 0 ∞ x n + 1 5 n (n + 1) = C − ∑ 0 ∞ x n n 5 n.
