  1. 2018-Schneebeli, Hans R. - Approximating cosine and sine functions numerically

    01 Mar 2018 | Contributor(s):: Hans Rudolf Schneebeli

    Abstract:How can function values ​​for sine or cosine be quickly and reliably numerically estimated?  We consider equal circular motions on the unit circle in the complex plane and find sine and cosine as solutions of a differential equation. The two functions can be numerically...
