make a table with two columns:
Column A contains time (or angle)
Column B contains the sin functions that uses the value in the same row of column A
Make the first row a header.
select A2 and B2, then fill down by grabbing (click and hold) the little circle at the bottom right of the selection then drag dow as needed.
now select columns A and B, then select the Scatter Chart from the Chart men u in the tool bar.

I agree : Grapher is the best to draw mathematical curves. For trigonometric functions the abscissa axis can be graduated in fractions of pi : 0 0,25pi 0,5pi etc.
The accuracy of a Grapher curve remains good when zooming a part of the curve. That is not true using a list on a Numbers or Excel spreadsheet.
If you are a new user of Grapher : a lot of free documentation available on <http://y.barois.free.fr/grapher/> (French and English)
