We recently upgraded to Office 2007. When we attempt to do a trendline in
Excel, the order of polynomials is always one below what it is stated to be
and the highest ordered polynomial is always wrong. (i.e. on a fourth order
polynomial, it will only display polynomials through the third order and in
the equation, the third ordered polynomial value is wrong, the others are
correct).

We tried installing the hot fix from KB 938541 as well as right clicking on
the equation for the chart and adding significant digits under Format
Trendline Label.

A sample file showing the problem can be downloaded from:
