Madhava is not only a pioneer in discovering an exact infinite series for pi, he is also a trail blazer in discovering rapidly convergent approximations and transformations of the series. In the same way, Madhava is not satisfied with merely enunciating the infinite series for the sine and cosine functions (the so called Newtons series), he also comes up with an algorithm (in terms of the famous mnemonics “vidvan”, “tunnabala”, etc.) for evaluating these functions accurately (correct to five decimal places) for an arbitrary argument..
