ABSTRACT This paper presents closed-form expressions for the series, , where the sum is from n = 1 to n = ∞. These expressions were obtained by recasting the series in a different form, followed by the use of certain relationships involving the elliptical nome. Among the values of x for which these expressions can be obtained are of the form: 2 l ∏ λ and 2 l ∏ λ , where l is an integer between – ∞ and ∞. The values of λ include 1, , , and 3. Examples of closed-form expressions obtained in this manner are first prese...
