Everything works as desired. Sin[30*Degree] Sin[31*Degree] Sin[29*Degree] 1/2 Sin[31*Degree] Sin[29*Degree] Compare with Sin[30*Degree]//N Sin[31*Degree]//N Sin[29*Degree]//N 0.5 0.515038 0.48481 and Sin[30*Degree]//N[#,40]& Sin[31*Degree]//N[#,40]& Sin[29*Degree]//N[#,40]& 0.5000000000000000000000000000000000000000 0.5150380749100542100816319363981382834161 0.4848096202463370290753796224157765682767 Regards Dimitris Steven Shippee wrote: > 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 ...
