How to make a sine wave graph

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

like:

Make the first row a header.

A2=ROW()*PI()/30

B2=SIN(A2)

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.

Shaun,

Functions can also be graphed with the built-in OS X application Grapher.

Jerry

Like Jerry indicated you can use Grapher (/Applications/Utilities/Grapher):

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)
