I want to figure out have excel take an equation for a trendline out of a
chart and paste it into a set of cells to calculate new values.

For example I have data at time 100, 200, 300 and 500, but want to
automatically have the equation of the trendline fitting my data copy over to
a set of cells where the intermadiate data for time 25,50,75 etc will be
calculated.
I typically fit a polonomial trendline?
