Example: Consider the power series ∑ (n=0 to ∞) (z+2i)^n / 3^n, where z is a complex number.y = 3x 1 − x2. and. y = 1 (x − 1)(x − 3). In Note 10.2.1, we state results regarding addition or subtraction of power series, composition of a power series, and multiplication of a power series by a power of the variable. For simplicity, we state the theorem for power series centered at x = 0.Before looking at series solutions to a differential equation we will first need to do a cursory review of power series. A power series is a series in the form, f (x) = ∞ ∑ n=0an(x −x0)n (1) (1) f ( x) = ∑ n = 0 ∞ a n ( x − x 0) n. where, x0 x 0 and an a n are numbers. We can see from this that a power series is a function of x x.The radius of convergence of a power series f centered on a point a is equal to the distance from a to the nearest point where f cannot be defined in a way that makes it holomorphic. The set of all points whose distance to a is strictly less than the radius of convergence is called the disk of convergence .Ratio Test. Suppose we have the series ∑an ∑ a n. Define, if L < 1 L < 1 the series is absolutely convergent (and hence convergent). if L > 1 L > 1 the series is divergent. if L = 1 L = 1 the series may be divergent, conditionally convergent, or absolutely convergent. A proof of this test is at the end of the section.2.
