What i'm looking to find is an equation that models the data so i can put
that equation into matlab. I know the length of the pendulum, g, etc., and
each set of data is taken every 1 cylce- the time measurements arent
significant for right now. What I mean't more was a trendline- for charts, i
know that you can create a linear regression, or "best fit" line and show the
equation. I am looking to do something like this, but for a sine curve. any
ideas? thanks!

You will have to do better than that to get homework help.
If you plot the data (XY plot) you will see a sine wave.
Were the measurements made every second, every 1/10 of second.....?
What exactly do you want to find - the length of the pendulum, the value of
g ?
You have not given us enough data.
The sine function in Excel is =SIN(A1) bit if A1 has degrees you need
=SIN(RADIANS(A1))

Hi,
I currently have a set of data for a pendelum, resembeling a sin function.
What functions or equations in excell can I use to find the sin function
representing this pendelum using my data?

Thanks!
