      Ramanujan-type approximations; recursive approximation to pi

    • Abstract


      We combine previously developed work with a variety of Ramanujan’s higher order modular equations to make explicit, in very simple form, algebraic approximations to π which converge with orders including 7, 11, 15 and 23.
