I found a site on Wikipedia that showed a lot of these expressions stacked together but unfortunately I cannot find it anymore. But that isn't a problem, when looking for the individual functions like "natural logarithm", you can find the formulas there is well. So what seemed to be a neat trick to calculate sine and cosine is growing into a nice tool for calculating other functions as well. Using tables has one advantage: speed. But the downside: they occupy space. So I will program two versions: one with tables and one where all needed values are calculated. But that leads to another question: I think Bernoulli numbers can be calculated but that will cost space as well. And TAN = SIN / COS so no calculations for the Bernoulli numbers needed at all. FYI: that's how GWBASIC and Commodore do it.
