Calculating sine to an absurd number of digits

Suppose you wanted to calculate sin(x) to a million decimal places using a Taylor series. How many terms of the series would you need? You can use trig identities to reduce the problem to finding sin(x) for |x| ≤ 1. Let’s take the worst case and assume we want to calculate sin(1). The series for […] The post Calculating sine to an absurd number of digits first appeared on John D. Cook....
