To perform an infinite sigma notation (Σ), use the formula Σ from n=1 to ∞ of a sequence. For example, for the sequence 1/n^2, write out the series as Σ (1/n^2) from n=1 to ∞. If the series converges, you can use mathematical techniques like comparison tests or integral tests to find the sum. For some series, known formulas exist; e.g., Σ (1/n^2) converges to π^2/6.
