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.

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?

Thanks in advance,

Steven Shippee
