Sorry, had one other question. You mentioned needing to fit a physical model
to my data. What does this mean?

1. Select the trendline equation, then use the Increase Decimal buttons on
the formatting toolbar to add decimal digits, or press Ctrl+1 (numeral one)
and click on the Number tab, and select a Scientific format with 15 places.

2. A 6th order poly fit is generally not well suited to fitting a curve
unless you are only looking to make the chart look pretty. As Martin Brown
stated in another thread just an hour ago:

You really need to fit a physical model to your data rather than the highest
order polynomial available.

I used a 6th degree polynomial trendline to smooth a curve on a chart. I
selected the option for printing the trendline formula on the chart so I
could use it in my calculations, but the numbers in the equation are
rounded
so that I don't get the right results. Is there any way that I can output
the equation with more significant figures shown?
