Steven, Because Mathematica returns exact results and it has no further simplifications for 29 and 31 Degree. Use N if you want approximate number results. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Steven Shippee [mailto:slshippee at comcast.net] What is happening here: Sin[30*Degree] Sin[31*Degree] Sin[29*Degree] which makes it appear that only the first line of input works? However, if I do something like: \!\(Sin[\(29*Pi\)\/180. ]\) I get the expected result ... I'm sure it is me, what am I missing in that I think I am not seeing consistent behavior?
