WebFeb 24, 2016 · The equation is read, "f of n is theta g of n". Formal Definition: f(n) = Θ (g(n)) means there are positive constants c 1, c 2, and k, such that 0 ≤ c 1 g(n) ≤ f(n) ≤ c 2 g(n) for all n ≥ k. The values of c 1, c 2, and k must be fixed for the function f and must not depend on n. Also known as asymptotically tight bound, theta.
