Using SimpleMath to Compute Recursively Converging Series The coding script SimpleMath , supported by Function Calculator , is highly useful for computing recurrence relations that converge systematically by 1. Let’s consider the following infinite series: 1 + 1/2 + 1/4 + 1/8 + ... + 1/2^n + ... This series sums an infinite sequence where each term is half of the previous one. Deriving the Recurrence Relation To compute this series, let’s first define its sum as : S = 1 + 1/2 + 1/4 + 1/8 + ... + 1/2^n + ... Now, let's multiply by : (1/2)*S = 1/2 + 1/4 + 1/8 + ... + 1/2^n + ... Since this new series is essentially with the first term 1 removed, we can express it as: (1/2)*S = S - 1 Solving for S, we get: S = 1 + (1/2) * S Implementing in SimpleMath Using SimpleMath , we can code this recurrence relation as follows: def S(n) = 1 + (1/2) * S(n-1); S(0) = 0; Here, S(n) and S(n-1) represent the sum S in our recurrence logic. Since S(n) and S(n-1) are nearly id...
