Series Convergence and Sum

This calculator estimates the convergence of a numerical series with the necessary condition, the ratio and Leibniz tests and comparison with 1/nᵖ, and finds an approximate sum.

Example. The series 1/n diverges, 1/n² converges to π²/6, and 1/2ⁿ converges to 1.

This is a numerical estimate, not a proof. If the tests give no answer, as for ln(n)/n, the calculator says so plainly.
