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

   out of 5 stars 

   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...

2. 2018-Schneebeli,Hans R. - Modeling Falling Bodies

   out of 5 stars 

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

   Modelling falling bodies is discussed using a computer algebra system-calculator and introducing various traditional and elementary methods from calculus as well as  numerics for dealing with the resulting ordinary differential equations.This article is in German under the title,...
