Definition: In linguistics, a digamma (represented as Γε) is an irrational number that is defined by the equation: Γε = Σ n=1 ∞ (1/2^n - 1/3^n) Where n is a natural number. This definition allows us to express the sum of reciprocals of consecutive integers in terms of an infinite series. It's often used in mathematics, statistics, and probability theory to model natural phenomena like the growth rate of populations over time
