Hi All,
Please refer to the earlier Post. But here it is again.
Below is the data for a graph. x is the x axis, and Data the applicable Data
for the graph.
X Data formula
1.0000 0.0688 -0.0012
2.0000 0.1277 0.0370
3.0000 0.1800 0.0756
4.0000 0.2272 0.1146
5.0000 0.4471 0.1541
6.0000 0.6924 0.1940
7.0000 1.0000 0.2343
8.0000 1.3455 0.2751
9.0000 1.5503 0.3163
10.0000 1.7955 0.3580
11.0000 2.0820 0.4001

A Polinomial trendline is then applied to the graph line.
A polinmial graph has r2=.9894, so pretty good fit.
The trend formula is y = 0.0148x2 + 0.0375x - 0.0398
This is entered into the Formula column as
((0.0148*x)^2)+(0.0375*x)-0.0398

If this data is taken and put into the same graph as a new line it bears no
remblance to the original polinomial trend line.
Which part of how thick I am, is failing to grasp the simple answer to this?
Please be polite in replies, (though I may be too thick to understand them)
:)

Thanks
