Thanks Tony, but I'd already assumed there are so many degrees per radian. What intrigued me was the way that series expressed the cosine function without needing to incorporate any such conversion factor and what was special about radians as opposed to degrees which enables this. In the same vein, I was wondering if there was any similarly elegant and simple series which could do the same for degrees.
